@c Notes about embedded man page:
|
|
@c This texinfo code contains the necessary info to produce a man page
|
|
@c which resembles much the version of xorriso.1 from which this code
|
|
@c was originally derived in march 2010.
|
|
@c One can produce the man page by applying the following rules:
|
|
@c The first line gets discarded.
|
|
@c Line start "@c man " will become "", the remainder is put out unaltered.
|
|
@c Lines "@*" will be converted to ".br"
|
|
@c "@c man-ignore-lines N" will discard N following lines.
|
|
@c "@c man-ignore-lines begin" discards all following lines
|
|
@c up to "@c man-ignore-lines end".
|
|
@c Line blocks of "@menu" "@end menu" will be discarded.
|
|
@c "@item word words" becomes "\fBword\fR words".
|
|
@c @b{...}, @command{...}, @dfn{...}, @emph{...}, @strong{...}
|
|
@c get mapped to \fB...\fR .
|
|
@c @abbr{...}, @code{...}, @file{...}, @i{...}, @option{...}, @r{...},
|
|
@c @ref{...}, @samp{...},@var{...}, get mapped to ... .
|

@c @email{...} gets mapped to <...> .
|
|
@c Mapped {...} content is subject to the rules except {...} mapping.
|
|
@c @minus{} will become "-".
|
|
@c @@ , @{, @} will get stripped of their first @.
|
|
@c Other lines which begin by "@" will be discarded.
|
|
@c In lines not stemming from "@c man", "\" becomes "\\"
|

@c man .PP
|
|
@command{xorrisofs}
|
|
produces Rock Ridge enhanced ISO 9660 filesystems and add-on sessions to
|
|
such filesystems. Optionally it can produce Joliet directory trees too.
|
|
@*
|
|
@sp 1
|
|
@c man .PP
|
|
@command{xorrisofs} understands options of program mkisofs from cdrtools by
|
|
Joerg Schilling.
|
|
Its implementation is part of program xorriso which shares no source
|
|
code with cdrtools.

@cindex ECMA-119, _definition
|
|
@strong{ISO 9660}
|
|
(aka @strong{ECMA-119}) is a read-only filesystem that is mainly used for
|
|
optical media CD, DVD, BD, but may also reside on other storage devices like
|
|
disk files, USB sticks or disk partitions. It is widely readable by many
|
|
operating systems and by boot facilities of personal computers.
|
|
@*
|
|
ISO 9660 describes directories and data files by
|
|
very restricted filenames with no distinction of upper case and lower case.
|
|
Its metadata do not comply to fundamental POSIX specifications.
|
|
@*
|
|
@cindex Rock Ridge, _definition
|
|
@strong{Rock Ridge}
|
|
is the name of a set of additional information which enhance
|
|
an ISO 9660 filesystem so that it can represent a POSIX compliant filesystem
|
|
with ownership, access permissions, symbolic links, and other attributes.
|
|
Rock Ridge allows filenames of up to 255 bytes and paths of up to
|
|
1024 bytes.
|
|
@*
|
|
xorrisofs produces Rock Ridge information by default. It is strongly
|
|
discouraged to disable this feature.
|
|
@*
|
|
@cindex Joliet, _definition
|
|
@strong{Joliet}
|
|
is the name of an additional directory tree which provides
|
|
filenames up to 64 characters encoded as UTF-16.
|
|
A Joliet tree is mainly interesting for reading the ISO image by
|
|
operating systems of Microsoft Corporation.
|
|
Production of this directory tree may be enabled by option -J.
|
|
@*
|
|
@cindex ISO 9660:1999, _definition
|
|
@strong{ISO 9660:1999}
|
|
is the name of an additional directory tree which provides longer
|
|
filenames. It allows single file names to have up to 207 characters.
|
|
It might be of use with some older computer system boot
|
|
facilities which read neither Rock Ridge nor Joliet but
|
|
need longer filenames nevertheless.
|
|
Production of this directory tree may be enabled by option -iso-level 4.
|
|
@*
|
|
@cindex HFS+, _definition
|
|
@strong{HFS+}
|
|
is the name of a filesystem which is normally used for writing and reading
|
|
on hard disks and similar devices. It is possible to embed a HFS+ partition
|
|
into the emerging ISO 9660 image and to mark it by Apple Partition Map
|
|
entries. This interferes with options which copy data into the first 32 KiB
|
|
of the ISO image, like -G or -isohybrid-mbr. See option -hfsplus.
|
|
@*
|
|
The main purpose for having an embedded HFS+ partition is booting of
|
|
certain models of Apple computers.

@chapter Inserting files into the ISO image
|

@c man .PP
|
|
@command{xorrisofs} deals with two kinds of file addresses:
|
|
@*
|
|
@cindex disk_path, _definition
|
|
@strong{disk_path}
|
|
is a path to an object in the local filesystem tree.
|
|
@*
|
|
@cindex iso_rr_path, _definition
|
|
@strong{iso_rr_path}
|
|
is the Rock Ridge address of a file object in the ISO image.
|
|
If no Rock Ridge information shall be stored in an emerging ISO, then the
|
|
names will get mapped to ISO 9660 names of limited length and character set.
|
|
@cindex pathspec, _definition
|
|
@*
|
|
@sp 1
|
|
@c man .PP
|
|
A program argument is handled as a @strong{pathspec}, if it is not
|
|
recognized as original mkisofs option or additional @command{xorrisofs} option.
|
|
A pathspec depicts an input file object by a disk_path.
|
|
If option -graft-points is not present, then the behavior depends on the
|
|
file type of disk_path. Directories get merged with the /-directory of the
|
|
ISO image. Files of other types get copied into the /-directory.
|
|
@*
|
|
If -graft-points is present then each pathspec gets split at the first
|
|
occurrence of the =-character.
|
|
The part before the = is taken as @strong{target}, i.e. the iso_rr_path for
|
|
the file object in the ISO image. The part after the first = is taken
|
|
as @strong{source}, i.e. the disk_path of the input object.
|
|
@*
|
|
It is possible to make =-characters part of the iso_rr_path by preceding
|
|
them with a \-character. The same must be done for \-characters which
|
|
shall be part of the iso_rr_path.
|
|
@*
|
|
@sp 1
|
|
@c man .PP
|
|
If the source part of the pathspec leads to a directory, then all files
|
|
underneath this directory get inserted into the image, too.
|
|
It is possible to exclude particular files from being inserted
|
|
by help of option -m.
|
|
@*
|
|
In case that target already exists, the following rules apply:
|
|
Directories and other files may overwrite existing non-directories.
|
|
Directories get merged with existing directories.
|
|
Non-directories may not overwrite existing directories.

@c man \fBRelation to program xorriso:\fR

@c man .br
|
|
@cindex xorriso, mkisofs emulation
|
|
@command{xorrisofs} is actually a command mode of program @strong{xorriso},
|
|
which gets entered either by xorriso command "-as mkisofs" or by
|
|
starting the program by one of the names "xorrisofs", "mkisofs",
|
|
"genisoimage", or "genisofs".
|
|
@*
|
|
This command mode can be left by argument "@minus{}@minus{}" which leads
|
|
to generic xorriso command mode. See @strong{man xorriso} for its description.
|
|
@*
|
|
@sp 1
|
|
@c man .PP
|
|
xorriso performs image reading and writing by help of libburn, which is
|
|
mainly intended for optical drives, but also operates on all POSIX
|
|
file types except directories.
|
|
@*
|
|
The program messages call any image file a "drive". File types which are not
|
|
supported for reading are reported as "blank". The reported free media
|
|
space may be quite fictional.
|
|
@*
|
|
Nevertheless @command{xorrisofs} does not operate directly on optical drives,
|
|
but rather forces libburn to regard them as general device files.
|
|
So for writing of sequential optical media (CD, DVD-R, DVD+R, BD-R)
|
|
one will have to use a burn program. E.g the cdrecord emulation of xorriso.
|

If they are missing then a new image is composed from scratch.

Set the path from which to load the existing ISO image directory tree
|
|
on which to base the upcoming directory tree as add-on session.
|
|
The path must lead to a random-access readable file object.
|
|
On GNU/Linux: regular data files or block device files.
|
|
@*
|
|
A special kind of pseudo disk_path has the form "/dev/fd/"number.
|
|
It depicts the open file descriptor with the given number, regardless whether
|
|
the operating system supports this feature by file nodes in /dev/fd or not.
|
|
E.g. /dev/fd/3 is file descriptor 3 which was opened by the program that
|
|
later started xorriso.

|
|
Set the 2 KiB block address last_session_start from where to read the
|
|
ISO image out of the file given by option -M.
|
|
@*
|
|
Separated by a comma, set the next_writeable_address to which the
|
|
add-on session will finally be written. Decisive is actually the block
|
|
address which the intended readers will have to use as superblock address
|
|
on the intended medium.
|
|
@*
|
|
Both values can be inquired from optical media by help of burn programs
|
|
and cdrecord option -msinfo. xorriso itself can obtain it in its

cdrecord emulation.

Enable the production of SUSP entries "ZF" instead of "Z2" with zisofs2
|

compressed files. Unaware Linux kernels complain about zisofs2 "ZF" by
|
|
"Unknown ZF compression algorithm" and thus leave a mark in the system log.

@cindex Incremental insertion, enable, -old-root
|
|
Enable incremental insertion of files into the loaded image.
|
|
The effective target and source addresses of given pathspecs get compared
|
|
whether the target already exists in the ISO image and is still identical
|
|
to the source on disk. Metadata in the ISO image will get adjusted, if they
|
|
differ from those on disk.
|
|
New files and files with changed content will get newly added.
|
|
Target files which do not exist in any of the according pathspec sources
|
|
will get removed from the ISO directory tree.
|
|
@*
|
|
If the effective setting of -root differs from the iso_rr_path given
|
|
with -old-root, then the files underneath the -old-root directory get cloned
|
|
underneath the -root directory. Cloning happens before file comparison.

@cindex Incremental insertion, disable disk ino, @minus{}@minus{}old-root-no-ino
|
|
Disable recording and use of disk inode numbers.
|
|
If no disk inode numbers are recorded, then option -old-root will have
|
|
to read disk file content and compare it with the MD5 checksum that is
|
|
recorded in the ISO image.
|
|
@*
|
|
With recorded disk inode numbers and with credible ctime and mtime,
|
|
it is possible to detect potential changes in the content without actually
|
|
reading it.
|
|
A loophole remains if multiple different filesystems may get mounted
|
|
at the same directory, like it is habit with /mnt.
|
|
In this case one has to use option @minus{}@minus{}old-root-devno
|

or disable the inode number shortcut by @minus{}@minus{}old-root-no-ino.

Enable comparison of recorded device numbers together with recorded
|
|
inode numbers. This works only with good old stable device numbers which
|
|
get out of fashion, regrettably. If the hard disk has a different
|
|
device number after each reboot, then this comparison will see all
|
|
files as changed and thus prevent any incremental size saving.

it with disk file content.

It depicts the open file descriptor with the given number, regardless whether

E.g. /dev/fd/4 is file descriptor 4 which was opened by the program that

The default with xorriso mkisofs emulation is @minus{}@minus{}stdio_sync "off".

xorriso uses an inner fifo buffer with default size 4 MiB. So forcing

|
|
Attribute a LBA weight number to regular files. If iso_rr_path leads

to a directory then all regular files underneath will get the weight_number.
|
|
@*
|
|
The weight_number may range from -2147483648 to 2147483647.
|
|
The higher it is, the lower will be the block address of the file data

in the emerging ISO image.
|
|
Currently the El Torito boot catalog has a hardcoded weight of 1 billion.

Normally it should occupy the block with the lowest possible address.

|
|
@*
|
|
Only the last @minus{}@minus{}sort-weight-list or

Notes for the case that this feature is used within a sequence of generic

|
|
@*
|

Several such commands may be used to apply more than one weight file.

@*
|
|
Data files which are loaded by -indev or -dev get a weight between 1 and
|
|
2 exp 28 = 268,435,456, depending on their block address. This shall keep

them roughly in the same order if the write method of modifying is applied.

The standard ECMA-119 demands that no path in the image shall have more
|
|
than 8 name components or 255 characters. Therefore it would be necessary
|
|
to move deeper directory trees to a higher directory. Rock Ridge offers an
|
|
opportunity to let these relocated directories appear at their original
|
|
deep position, but this feature might not be implemented properly by
|
|
operating systems which mount the image.
|
|
@*
|
|
Option -D disables this deep directory relocation, and thus violates
|
|
ISO 9660 specs.
|
|

the options -rr_reloc_dir and -hide-rr-moved.

|
|
Enable the relocation of deep directories and thus avoid ECMA-119 file paths
|
|
of more than 8 name components or 255 characters. Directories which lead to
|
|
such file paths will get moved to a directory in the root directory of the
|
|
image. Its name gets set by this option.
|
|
It is permissible to use the root directory itself.
|
|
@*
|
|
The overall directory tree will appear originally deep when interpreted as
|
|
Rock Ridge tree. It will appear as re-arranged if only ECMA-119 information

is considered.

@*
|

If the given relocation target directory does not already exist when image

@cindex HFS+, enables production
|
|
Enable the production of an additional HFS+ filesystem inside the ISO 9660
|
|
image and mark it by Apple Partition Map (APM) entries in the System Area,
|
|
the first 32 KiB of the image.
|
|
@*
|
|
This may collide with options like -G or -isohybrid-mbr which submit user data
|
|
for inclusion in the same address range.
|
|
The first 8 bytes of the System Area get overwritten by
|
|
@{ 0x45, 0x52, 0x08 0x00, 0xeb, 0x02, 0xff, 0xff @}
|
|
which can be executed as x86 machine code without negative effects.
|
|
So if an MBR gets combined with this feature, then its first 8 bytes
|
|
should contain no essential commands.
|
|
@*
|
|
The next blocks of 2 KiB in the System Area will be occupied by APM entries.
|
|
The first one covers the part of the ISO image before the HFS+ filesystem
|
|
metadata. The second one marks the range from HFS+ metadata to the end
|
|
of file content data. If more ISO image data follow, then a third partition
|
|
entry gets produced. Other features of xorriso might cause the need for
|
|
more APM entries.
|
|
@*
|
|
Be aware that HFS+ is case-insensitive although it can record file names
|
|
with upper-case and lower-case letters. Therefore, file names from the iso_rr
|
|
name tree may collide in the HFS+ name tree. In this case they get changed
|
|
by adding underscore characters and counting numbers. In case of very long
|
|
names, it might be necessary to map them to "MANGLED_...".
|
|
@*
|
|
WARNING:
|
|
@*
|
|
The HFS+ implementation in libisofs has a limit of 125,829,120 bytes for the
|
|
size of the overall directory tree. This suffices for about 300,000 files
|
|
of normal name length. If the limit gets exceeded, a FAILURE event will be

issued and the ISO production will not happen.

@section El Torito Bootable ISO images
|
|
@c man .PP
|
|
The precondition for a bootable ISO image is to have in the ISO image
|
|
the files of a boot loader. The boot facilities of computers get
|
|
directed to such files, which usually execute further program files
|
|
from the ISO image.
|
|
@command{xorrisofs} can produce several kinds of boot block or boot record,
|
|
which become part of the ISO image, and get interpreted by the according
|
|
boot facility.

@cindex El Torito, _definition
|
|
An @strong{El Torito}
|
|
boot record points the bootstrapping facility to a boot catalog
|
|
with one or more boot images, which are binary program files stored in
|
|
the ISO image.
|
|
The content of the boot image files is not in the scope of El Torito.
|
|
@*
|
|
xorriso composes the boot catalog according to the boot image
|
|
files given and structured by options -b, -e, -eltorito-alt-boot,
|
|
and @minus{}@minus{}efi-boot. Often it contains only one entry.
|
|
@*
|
|
Normally the boot images are data files inside the ISO filesystem. By
|
|
special path "--interval:appended_partition_NNN:all::" it is possible to
|
|
refer to an appended partition. The number NNN gives the partition number
|
|
as used with the corresponding option -append_partition.
|
|
E.g.:
|
|
@*
|
|
-append_partition 2 0xef /tmp/efi.img
|
|
@*
|
|
-e --interval:appended_partition_2:all::

El Torito gets interpreted by boot facilities PC-BIOS and EFI.
|
|
Most bootable GNU/Linux CDs are equipped with ISOLINUX or GRUB boot images
|
|
for PC-BIOS.
|

@*
|

@command{xorrisofs} supports the example options out of the ISOLINUX wiki,

of the following components, separated by colon ':'
|
|
@*
|
|
"@minus{}@minus{}interval:"Flags":"Interval":"Zeroizers":"Source
|
|
@*
|

The component "@minus{}@minus{}interval" states that this is not
|
|
a plain disk path but rather a interval reader description string.
|
|
@*
|

The component Flags modifies the further interpretation:
|
|
@*
|
|
"local_fs" demands to read from a file depicted by the path in Source.
|
|
@*
|
|
"imported_iso" demands to read from the -indev. This works only if -outdev
|
|
is not the same as -indev. The Source component is ignored.
|
|
@*
|
|
"appended_partition_NNN" with a decimal number NNN works only for options
|
|
which announce El Torito boot image paths: -b, -e, --efi-boot. The number gives
|
|
the partition number as used with the corresponding option -append_partition.
|
|
@*
|
|
The component Interval consists of two byte address numbers separated by a "-" character. E.g. "0-429" means to read bytes 0 to 429.
|
|
@*
|
|
The component Zeroizers consists of zero or more comma separated strings.
|
|
They define which part of the read data to zeroize. Byte number 0 means
|
|
the byte read from the Interval start address.
|
|
Each string may be one of:
|
|
@*
|
|
"zero_mbrpt" demands to zeroize the MBR partition table if
|
|
bytes 510 and 511 bear the MBR signature 0x55 0xaa.
|
|
@*
|
|
"zero_gpt" demands to check for a GPT header in bytes 512 to 1023,
|
|
to zeroize it and its partition table blocks.
|
|
@*
|
|
"zero_apm" demands to check for an APM block 0 and to zeroize
|
|
its partition table blocks.
|
|
@*
|
|
Start_byte"-"End_byte demands to zeroize the read-in bytes beginning
|
|
with number Start_byte and ending after End_byte.
|
|
@*
|
|
The component Source is the file path with flag "local_fs", and ignored with
|
|
flag "imported_iso".
|

@*
|
|
Byte numbers may be scaled by a suffix out of @{k,m,g,t,s,d@} meaning
|
|
multiplication by @{1024, 1024k, 1024m, 1024g, 2048, 512@}. A scaled value

end number depicts the last byte of the scaled range.

|
|
Patch the System Area by a simple PC-DOS partition table where partition 1

claims the range of the ISO image but leaves the first block unclaimed.
|
|
This is mutally exclusive to option -isohybrid-mbr.

@kindex @minus{}@minus{}mbr-force-bootable Enforce MBR bootable/active flag
|

@cindex Bootability, bootable MBR partition, @minus{}@minus{}mbr-force-bootable
|
|
Enforce an MBR partition with "bootable/active" flag if options like
|
|
@minus{}@minus{}protective-msdos-label or @minus{}@minus{}grub2-mbr are given.
|
|
These options normally cause the flag to be set if there is an
|
|
MBR partition of type other than 0xee or 0xef.
|
|
If no such partition exists, then no bootflag is set, unless
|
|
@minus{}@minus{}mbr-force-bootable forces creation of a dummy partition
|
|
of type 0x00 which covers only the first block of the ISO image.
|
|
@*
|
|
If no bootable MBR is indicated by other options and a partition gets created
|
|
by -append_partition, then @minus{}@minus{}mbr-force-bootable causes a
|
|
bootflag like it would do with e.g. @minus{}@minus{}protective-msdos-label.

@cindex Mountability, by non-trivial partition 1, -partition_offset
|
|
Cause a partition table with a single partition that begins at the
|
|
given block address. This is counted in 2048 byte
|
|
blocks, not in 512 byte blocks. If the block address is non-zero then it must
|
|
be at least 16. Values larger than 16 are hardly of use.
|
|
A non-zero partition offset causes two superblocks to be
|
|
generated and two sets of directory trees. The image is then mountable from its
|
|
absolute start as well as from the partition start.
|
|
@*
|
|
The offset value of an ISO image gets preserved when a new session is added
|
|
to a loaded image.
|
|
So the value defined here is only in effect if a new ISO image gets written.

@cindex MBR, sectors per head, -partition_sec_hd
|
|
Set the number of sectors per head for the MBR partition table.
|
|
0 chooses a default value. Maximum is 63.
|
|
@*
|
|
The product partition_sec_hd * partition_hd_cyl * 512 is the cylinder size.
|
|
It should be divisible by 2048 in order to make exact alignment possible.
|
|
With appended partitions and -appended_part_as_gpt there is no limit for
|
|
the number of cylinders. Else there may be at most 1024 of them.
|
|
If the cylinder size is too small to stay below the limit,
|
|
then appropriate values of partition_hd_cyl are chosen with
|
|
partition_sec_hd 32 or 63. If the image is larger than 8,422,686,720 bytes,
|
|
then the cylinder size constraints cannot be fulfilled for MBR.
|
|
They seem not overly important anyway.

Flat block addresses in partition tables are good for 1 TiB.

It is prescribed by isohybrid specs and it seems to please program fdisk.
|

Cylinder size must be divisible by 2048.
|
|
Images larger than 8,323,596,288 bytes cannot be aligned in MBR partition

Mode "on" causes alignment by padding with option
|

@minus{}@minus{}protective-msdos-label too.
|

Mode "all" is like "on" but also pads up partitions from -append_partition
|

to an aligned size.

Mode "off" disables alignment unconditionally.

@cindex MBR, GPT, append partition, -append_partition
|
|
Cause a prepared filesystem image to be appended to the ISO image and to be
|
|
described by a partition table entry in a boot block at the start of the
|
|
emerging ISO image. The partition entry will bear the size of the submitted
|
|
file rounded up to the next multiple of 2048 bytes or to the next multiple
|
|
of the cylinder size.
|
|
@*
|
|
Beware of subsequent multi-session runs. The appended partition will get
|
|
overwritten.
|
|
@*
|
|
partition_number may be 1 to 4. Number 1 will put the whole ISO image into
|
|
the unclaimed space before partition 1. So together with most xorriso MBR
|
|
or GPT features, number 2 would be the most natural choice.
|
|
@*
|
|
The type_code may be "FAT12", "FAT16", "Linux",
|
|
or a hexadecimal number between 0x00 and 0xff. Not all those numbers will
|
|
yield usable results. For a list of codes search the Internet for
|
|
"Partition Types" or run fdisk command "L".
|
|
If the partition appears in GPT then type_code 0xef is mapped to the EFI System
|
|
Partition Type GUID. All others get mapped to Basic Data Type GUID.
|
|
@*
|
|
type_code may also be a type GUID as plain hex string like
|
|
a2a0d0ebe5b9334487c068b6b72699c7 or as structured text like
|
|
EBD0A0A2-B9E5-4433-87C0-68B6B72699C7. It will be used if the partition is
|
|
mentioned in GPT. In MBR, C12A7328-F81F-11D2-BA4B-00A0C93EC93B will be mapped
|
|
to 0xef. Any other GUID will be mapped to 0x83.
|
|
In APM, 48465300-0000-11AA-AA11-00306543ECAC will be mapped to partition
|
|
type "Apple_HFS", any other to "Data".
|
|
@*
|
|
If some other command causes the production of GPT, then the appended

Instead of a disk_path, the word @minus{}@minus{}efi-boot-image may be given.

It exposes in GPT the content of the first El Torito EFI boot image as

EFI system partition. EFI boot images are introduced by options -e or

or whether the GUID is supplied by the user.
|
|
Value "random" is default. Value "modification-date" produces a low quality

|
|
@*
|
|
A string of 32 hex digits, or a RFC 4122 compliant GUID string may be used to

set the disk GUID directly. UEFI prescribes the first three components of
|
|
a RFC 4122 GUID string to be byte-swapped in the binary representation:

@*
|
|
If the use of libjte was enabled at compile time of xorriso, then
|
|
@command{xorrisofs} can produce a .jigdo and a .template file together with a
|
|
single-session ISO image. If not, then Jigdo options will cause a
|
|
FAILURE event, which normally leads to program abort.
|
|
@*
|
|
One may determine the ability for Jigdo by:
|

The .jigdo file contains checksums and symbolic file addresses.
|
|
The .template file contains the compressed ISO image with reference tags
|
|
instead of the content bytes of the listed files.
|
|
@*
|
|
Input for this process are the normal arguments for a @command{xorrisofs}
|
|
session with no image loaded, and a checksum file which lists those
|
|
data files which may be
|
|
listed in the .jigdo file and externally referenced in the .template file.
|
|
Each designated file is represented in the checksum file by a single text line:
|
|
@*
|
|
Checksum as hex digits, 2 blanks, size as 12 decimal digits or blanks, 2 blanks,
|
|
symbolic file address
|
|
@*
|
|
The kind of checksum is chosen by -jigdo "checksum_algorithm" with values "md5"
|
|
(32 hex digits) or "sha256" (64 hex digits).
|
|
It will also be used for the file address lines in the .jigdo file.

The default is "md5".

@*
|
|
The file address in a checksum file line has to bear the same basename as the

the file address is decisive for To=From mapping, not for file recognition.

directory of the ISO image, maintaining its name. If a directory is given,
|
|
then its files and sub-directories are copied into the root directory,
|

maintaining their names.

@sp 1
|
|
$ xorrisofs ... /home/me/datafile /tmp/directory
|

@section Perform multi-session runs
|
|
This example works for multi-session media only:
|
|
CD-R[W], DVD-R[W], DVD+R, BD-R.
|
|
Add cdrskin option @minus{}@minus{}grow_overwriteable_iso
|
|
to all -as cdrecord runs
|
|
in order to enable multi-session emulation on overwritable media.
|
|
@*
|
|
The first session is written like this:
|
|
@*
|
|
@sp 1
|
|
$ xorrisofs -graft-points \
|
|
@*
|
|
/tree1=prepared_for_iso/tree1 \
|
|
@*
|
|
| xorriso -as cdrecord -v dev=/dev/sr0 blank=fast -multi -eject -
|
|
@*
|
|
@sp 1
|
|
Follow-up sessions are written like this (the run of dd is only to give demons
|
|
a chance to spoil it):
|
|
@*
|
|
@sp 1
|
|
$ m=$(xorriso -as cdrecord dev=/dev/sr0 -msinfo)
|
|
@*
|
|
$ dd if=/dev/sr0 count=1 >/dev/null 2>&1
|
|
@*
|
|
$ xorrisofs -M /dev/sr0 -C $m -graft-points \
|
|
@*
|
|
/tree2=prepared_for_iso/tree2 \
|
|
@*
|
|
| xorriso -as cdrecord -v dev=/dev/sr0 -waiti -multi -eject -
|
|
@*
|
|
@sp 1
|
|
Always eject the drive tray between sessions.
|
|
@*
|
|
The run of xorriso -as mkisofs will read old sessions via the CD-ROM
|
|
driver of /dev/sr0. This driver might not be aware of the changed content
|
|
as long as the medium is not loaded again. In this case the previous session
|
|
would not be properly assessed by xorriso and the new session would contain
|
|
only the newly added files.
|
|
@*
|
|
Some systems have not enough patience with automatic tray loading and some
|
|
demons may interfere with a first CD-ROM driver read attempt from a freshly
|
|
loaded medium.
|
|
@*
|
|
When loading the tray manually, wait 10 seconds after the drive has stopped
|
|
blinking.
|
|
@*
|
|
A safe automatic way seems to be a separate run of xorriso for loading
|
|
the tray with proper waiting, and a subsequent run of dd which shall offer
|
|
itself to any problems caused by demons assessing the changed drive status.
|
|
If this does not help, insert a run of "sleep 10" between xorriso and dd.

@node ExGrowisofs, ExIncBackup, ExMkisofs, Examples
|
|
@section Let xorriso work underneath growisofs
|
|
growisofs expects an ISO formatter program which understands options -C and
|
|
-M. A variable is defined to override the hardcoded default name.
|
|
@*
|
|
@sp 1
|
|
$ export MKISOFS="xorrisofs"
|
|
@*
|
|
$ growisofs -Z /dev/dvd /some/files
|
|
@*
|
|
$ growisofs -M /dev/dvd /more/files
|
|
@*
|
|
@sp 1
|
|
If no "xorrisofs" is available on your system, then you will have to create
|
|
a link pointing to the xorriso binary and tell growisofs to use it. E.g. by:
|
|
@*
|
|
@sp 1
|
|
$ ln -s $(which xorriso) "$HOME/xorrisofs"
|
|
@*
|
|
$ export MKISOFS="$HOME/xorrisofs"
|
|
@*
|
|
@sp 1
|
|
One may quit mkisofs emulation by argument "@minus{}@minus{}" and make
|
|
use of all xorriso commands. growisofs dislikes options which
|
|
start with "-o" but -outdev must be set to "-".
|
|
So use "outdev" instead:
|
|
@*
|
|
@sp 1
|
|
$ growisofs -Z /dev/dvd @minus{}@minus{}for_backup @minus{}@minus{} \
|
|
@*
|
|
outdev - -update_r /my/files /files
|
|
@*
|
|
$ growisofs -M /dev/dvd @minus{}@minus{}for_backup @minus{}@minus{} \
|
|
@*
|
|
outdev - -update_r /my/files /files
|
|
@*
|
|
Note that @minus{}@minus{}for_backup is given in the mkisofs emulation.
|
|
To preserve the recorded extra data it must already be in effect, when
|
|
the emulation loads the image.

This changes the directory trees /open_source_project and /personal_mail
|
|
in the ISO image so that they become exact copies of their disk counterparts.
|
|
ISO file objects get created, deleted or get their attributes adjusted
|
|
accordingly.
|
|
@*
|
|
ACL, xattr, hard links and MD5 checksums will be recorded.

it is possible to access the session trees which represent the older backup

its option "session=".
|
|
@*

Multi-session media and most overwritable media written by xorriso can tell
|

the sbsectors of their sessions by xorriso option -toc:
|
|
@*
|
|
@sp 1
|
|
$ xorriso -dev /dev/sr0 -toc
|
|
@*
|
|
@sp 1

xorriso can print the matching mount command for a session number:
|
|
@*
|
|
@sp 1
|
|
$ xorriso -mount_cmd /dev/sr0 session 12 /mnt
|
|
@*
|
|
@sp 1

or for a volume id that matches a search expression:
|
|
@*
|

@sp 1
|
|
$ xorriso -mount_cmd /dev/sr0 volid '*2008_12_05*' /mnt
|
|
@*
|

Both yield on standard output something like:

Solaris does not offer the option to mount older sessions.
|
|
In order to keep them accessible, one may map all files to a file tree under

a session directory and accumulate those directories from session to session.
|
|
The -root tree is cloned from the -old-root tree before it gets

|
compared with the appropriate trees on disk.

|
@node ExBootable, , ExIncBckAcc, Examples

@section Create bootable images for PC-BIOS and EFI
|
|
The SYSLINUX/ISOLINUX boot loader suite is popular for booting PC-BIOS.
|
|
The ISOLINUX wiki prescribes to create on disk a directory ./CD_root and
|
|
to copy all desired files underneath that directory. Especially file
|
|
isolinux.bin shall be copied to ./CD_root/isolinux/isolinux.bin .
|
|
This is the boot image file.
|
|
@*
|
|
The prescribed mkisofs options can be used unchanged with @command{xorrisofs}:
|
|
@*
|
|
@sp 1
|
|
$ xorrisofs -o output.iso \
|
|
@*
|
|
-b isolinux/isolinux.bin -c isolinux/boot.cat \
|
|
@*
|
|
-no-emul-boot -boot-load-size 4 -boot-info-table \
|
|
@*
|
|
./CD_root
|
|
@*
|
|
@sp 1
|
|
Put it on CD by a burn program. E.g.:
|
|
@*
|
|
@sp 1
|
|
$ xorriso -as cdrecord -v dev=/dev/sr0 blank=as_needed output.iso
|
|
@*
|
|
@sp 1
|
|
@c man .sp 1
|
|
The image from above example will boot from CD, DVD or BD, but not from
|
|
USB stick or other hard-disk-like devices. This can be done by help of an
|
|
isohybrid MBR. Syslinux provides matching template files
|
|
as isohdp[fp]x*.bin . E.g. /usr/lib/syslinux/isohdpfx.bin .
|
|
@*
|
|
If a few hundred KB of size do not matter, then option -partition_offset
|
|
can be used to create a partition table where partition 1 starts not
|
|
at block 0. This facilitates later manipulations of the USB stick by
|
|
tools for partitioning and formatting.
|
|
@*
|
|
The image from the following example will be prepared for booting via MBR
|
|
and its first partition will start at hard disk block 64.
|
|
@*
|
|
It will also boot from optical media.
|
|
@*
|
|
@sp 1
|
|
$ xorrisofs -o output.iso \
|
|
@*
|
|
-b isolinux/isolinux.bin -c isolinux/boot.cat \
|
|
@*
|
|
-no-emul-boot -boot-load-size 4 -boot-info-table \
|
|
@*
|
|
-isohybrid-mbr /usr/lib/syslinux/isohdpfx.bin \
|
|
@*
|
|
-partition_offset 16 \
|
|
@*
|
|
./CD_root
|
|
@*
|
|
@sp 1
|
|
Become superuser and copy the image to the unpartitioned base device file
|
|
of the USB stick. On GNU/Linux this is e.g. /dev/sdb, not /dev/sdb1.
|
|
@*
|
|
CAUTION:
|
|
This will overwrite any partitioning on the USB stick and make
|
|
remaining data unaccessible.
|
|
@*
|
|
So first make sure you got the correct address of the intended device.
|
|
E.g. by reading 100 MiB data from it and watching it blinking:
|
|
@*
|
|
@sp 1
|
|
# dd bs=2K if=/dev/sdb count=50K >/dev/null
|
|
@*
|
|
@sp 1
|
|
Now copy the image onto it
|
|
@*
|
|
@sp 1
|
|
# dd bs=2K if=output.iso of=/dev/sdb
|
|
@*
|
|
@sp 1
|
|
@c man .sp 1
|
|
Now for EFI:
|
|
@*
|
|
The boot image file has to be the image of an EFI System Partition,
|
|
i.e. a FAT filesystem with directory /EFI/BOOT and boot files with
|
|
EFI prescribed names: BOOTIA32.EFI for 32 bit x86,
|
|
BOOTx64.EFI for 64 bit AMD/x86 (in UEFI-2.4 there is indeed a lower case "x"),
|
|
BOOTAA64.EFI for 64 bit ARM. The software in the FAT filesystem should be
|
|
able to find and inspect the ISO filesystem for boot loader configuration and
|
|
start of operating system. GRUB2 program grub-mkimage can produce such a
|
|
FAT filesystem with suitable content, which then uses further GRUB2
|
|
software from the ISO filesystem.
|
|
@*
|
|
EFI boot equipment may be combined with above ISOLINUX isohybrid for PC-BIOS
|
|
in a not really UEFI-2.4 compliant way, which obviously works well. It yields
|
|
MBR and GPT partition tables, both with nested partitions.
|
|
Assumed the EFI System Partition image is ready as ./CD_root/boot/grub/efi.img,
|
|
add the following options before the directory address ./CD_root:
|
|
@*
|
|
@sp 1
|
|
-eltorito-alt-boot -e 'boot/grub/efi.img' -no-emul-boot \
|
|
@*
|
|
-isohybrid-gpt-basdat \
|
|
@*
|
|
@sp 1
|
|
More compliant with UEFI-2.4 is to decide for either MBR or GPT and to
|
|
append a copy of the EFI System Partition in order to avoid overlap of
|
|
ISO partition and EFI partition. Here for MBR:
|
|
@*
|
|
@sp 1
|
|
-eltorito-alt-boot -e 'boot/grub/efi.img' -no-emul-boot \
|
|
-append_partition 2 0xef ./CD_root/boot/grub/efi.img \
|
|
@*
|
|
@sp 1
|
|
The resulting ISOs are supposed to boot from optical media and USB stick.
|
|
One may omit option -eltorito-alt-boot if no option -b is used to make
|
|
the ISO bootable via PC-BIOS.
|
|
@*
|
|
@sp 1
|
|
@c man .sp 1
|
|
For ISOs with pure GRUB2 boot equipment consider to use GRUB2 tool
|
|
grub-mkrescue as frontend to xorrisofs.
|
|
@*
|
|
@sp 1
|
|
@c man .sp 1
|
|
If you have a bootable ISO filesystem and want to know its equipment plus
|
|
a proposal how to reproduce it, try:
|
|
@*
|
|
@sp 1
|
|
$ xorriso -hfsplus on -indev IMAGE.iso \
|
|
-report_el_torito plain -report_system_area plain \
|

-print "" -print "======= Proposal for xorrisofs options:" \
|

If not --no_rc is given as the first argument then @command{xorrisofs}
|

attempts on startup to read and execute lines from the following files:

/etc/default/xorriso

@*
|

@sp 1
|
|
The files are read in the sequence given here, but none of them is required
|
|
to exist. The lines are not interpreted as @command{xorrisofs} options but
|
|
as generic xorriso commands. See man xorriso.
|
|
@c man .PP
|
|
After the xorriso startup files, the program tries one by one to open for
|
|
reading:
|
|
@*

./.mkisofsrc
|

$(dirname $0)/.mkisofsrc
|
|
@*
|
|
@sp 1
|
|
On success it interprets the file content and does not try further files.
|
|
The last address is used only if start argument 0 has a non-trivial dirname.
|
|
@*

The following environment variables influence the program behavior:
|
|
@*
|
|
HOME is used to find xorriso and mkisofs startup files.
|
|
@*
|
|
MKISOFSRC may be used to point the program to a mkisofs startup file.
|
|
@*
|
|
SOURCE_DATE_EPOCH belongs to the specs of reproducible-builds.org.
|
|
It is supposed to be either undefined or to contain a decimal number
|
|
which tells the seconds since january 1st 1970. If it contains a number,
|
|
then it is used as time value to set the default of
|
|
@minus{}@minus{}modification-date=.
|
|
@minus{}@minus{}gpt_disk_guid defaults to "modification-date".
|
|
The default of @minus{}@minus{}set_all_file_dates is then "set_to_mtime".
|
|
Further the "now" time for ISO nodes without disk source is then set to
|
|
the SOURCE_DATE_EPOCH value.
|
|
@*
|
|
Startup files and program options can override the effect of SOURCE_DATE_EPOCH.
