@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 "\fB\-word\fR words".
|
|
@c "@item word words" becomes "\fBword\fR words".
|
|
@c @strong{-...} gets mapped to \fB\-...\fR .
|
|
@c @strong{...} gets mapped to \fB...\fR .
|
|
@c @minus{} will become "-".
|
|
@c @@ , @{, @} will get stripped of their first @.
|
|
@c Other lines which begin by "@" will be discarded.
|

Its implementation is part of program xorriso which shares no source
|
|
code with cdrtools.

|
|
@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, _definiton
|
|
@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.
|
|
@*
|
|
Rock Ridge information is produced unconditionally with any xorrisofs image.
|
|
@*
|
|
@cindex Joliet, _definiton
|
|
@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, _definiton
|
|
@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.

@c man .PP
|
|
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. (Do not
|
|
confuse with the lowlevel ISO 9660 names visible if Rock Ridge gets ignored.)
|
|
@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 xorrisofs option.
|
|
A pathspec depicts an input file object by a disk_path.
|
|
If option -graft-points is not present, then this file object gets
|
|
copied into the /-directory of the ISO image.
|
|
@*
|
|
If -graft-points is present then each pathspec gets split at the first
|
|
occurence of the =-character.
|
|
The part before the = is taken as @strong{target}, the iso_rr_path for
|
|
the file object in the ISO image. The part after the first = is taken
|
|
as @strong{source}, the disk_path of the input object.
|
|
@*
|
|
It is possible to make =-characters part of the iso_rr_path by preceeding
|
|
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.

@cindex xorriso, mkisofs emulation
|
|
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 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.

|
|
@c man .PP
|
|
The following options control loading of an existing ISO image for the purpose
|
|
of preparing a suitable add-on session.
|
|
If they are missing then a new image is composed from scratch.
|
|
@table @asis

|
@item -M disk_path
|

@kindex -M set path for loading existing ISO image
|
|
@cindex Session, select path, -M, -prev-session, -dev
|
|
Set the path from which to load the existing ISO image directory tree
|
|
on which to base the upcomming 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.
|
|
@c man .TP
|
|
@item -prev-session disk_path
|
|
@kindex -prev-session set path for loading existing ISO image
|
|
Alias of -M.
|

@kindex -dev set path for loading existing ISO image
|

@item -C last_session_start,next_writeable_address
|
|
@kindex -C set load address and write address offset
|
|
@cindex Session, set load and write address, -C, -cdrecord-params
|
|
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 media.
|
|
@*
|
|
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:
|
|
@*
|
|
values=$(xorriso -as cdrecord dev=/dev/... -msinfo)
|
|
echo $values
|
|
@*
|
|
Option -C may be used without option -M to create an ISO image from
|
|
scratch and prepare it for being finally written to a block address
|
|
other than 0. Parameter last_session_start should then be set to 0.
|
|
@c man .TP
|

|
|
Whitespace outside of quotes will be discarded. On the other hand it is
|
|
possible to represent pathspecs which contain newline characters.
|
|
@*
|
|
The double quotation mark " and the single quotation mark ' can be used to
|
|
enclose whitespace and make it part of pathspecs. Each mark
|
|
type can enclose the marks of the other type. A trailing backslash \ outside
|

@cindex Disk files, exclude, -m, -exclude, -x, -old-exclude
|
|
Exclude files from being inserted into the image. Silently ignored are

|
those files of which the disk_path matches the given shell parser pattern.
|
|
If no /-character is part of the pattern, then it gets matched against
|
|
the leaf name of the disk file.

as produced by program mkzftree. These files will get equipped with the
|
|
necessary meta data so that a Linux kernel will recognize them and
|
|
deliver their content in uncompressed form.

@kindex -root redirect ISO root directory
|
|
@cindex ISO root directory, redirect, -root
|
|
Insert all files under the given iso_rr_path. If option -graft-points is given,
|
|
then iso_rr_path is prepended to each target part of a pathspec.
|
|
@*
|
|
The default for -root is "/".

@c man .TP
|
|
@item -old-root iso_rr_path
|
|
@kindex -old-root enable incremental insertion
|
|
@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 eventually get adjusted.
|
|
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.
|
|
@c man .TP
|
|
@item @minus{}@minus{}old-root-no-ino
|
|
@kindex @minus{}@minus{}old-root-no-ino disable disk ino with -old-root
|
|
@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.
|
|
@c man .TP
|
|
@item @minus{}@minus{}old-root-devno
|
|
@kindex @minus{}@minus{}old-root-devno enable disk idevno with -old-root
|
|
@cindex Incremental insertion, enable disk devno, @minus{}@minus{}old-root-devno
|
|
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.
|
|
@c man .TP
|
|
@item @minus{}@minus{}old-root-no-md5
|
|
@kindex @minus{}@minus{}old-root-no-md5 disable MD5 with -old-root
|
|
@cindex Incremental insertion, disable MD5, @minus{}@minus{}old-root-no-md5
|
|
Disable recording and eventual use of MD5 checksums for data file content.
|
|
If neither checksums and nor disk inode numbers are recorded, then
|
|
option -old-root will have to read ISO image file content when comparing
|
|
it with disk file content.

|
|
@cindex Output file, set address, -o, -output
|
|
Set the output file address for the emerging ISO image.
|
|
If the address exists as regular file, it will be truncated to length 0
|
|
when image production begins. It may not already exist as directory.
|
|
If it does not exist yet then its parent directory must exist and
|
|
a regular file will get created.

@*
|
|
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/4 is file descriptor 4 which was opened by the program that
|
|
later started xorriso.
|
|
@*
|
|
Default is standard output (/dev/fd/1) which may also be set by disk_path "-".

@kindex @minus{}@minus{}stdio_sync control forced output to disk files
|

@cindex Forced output, control, @minus{}@minus{}stdio_sync
|
|
Set the number of bytes after which to force output to disk
|
|
in order to keep the memory from being clogged with lots of
|
|
pending data for slow devices. Default "on" is the same as "16m".
|
|
Forced output can be disabled by "off".
|
|
@*
|
|
xorriso uses an inner fifo buffer with default size 4 MiB. So forcing
|
|
the operating system i/o cache to disk does not necessarily block the
|
|
simultaneous production of more image content.

|

Write a second superblock with the first session into random-access

files. If further sessions get appended and the first superblock gets updated,
|
|
then the second superblock will not be overwritten. This allows to still
|
|
mount the first session and to find the start blocks of the further sessions.
|

@*

The price is 64 KiB extra space consumption. If -partition_offset is non-zero,

|
|
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.

|
|
Add 300 KiB to the end of the produced ISO image. This circumvents possible
|
|
read errors from ISO images which have been written to CD media in TAO mode.
|
|
The additional bytes are claimed as part of the ISO image if not --emul-toc

This is safe if the image is not meant to be written on CD or if it
|
|
gets written to CD as only track in write mode SAO.

|
|
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.
|
|
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, _definiton
|
|
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, -el-torito-alt-boot,
|
|
and @minus{}@minus{}efi-boot. Often it contains only one entry.
|
|
@*
|
|
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.
|
|
@*
|
|
xorrisofs supports the example options out of the ISOLINUX wiki,

@kindex -isohybrid-mbr Install ISOLINUX isohybrid MBR
|

@cindex Bootability, install ISOLINUX isohybrid MBR, -isohybrid-mbr
|
|
Install disk_path as ISOLINUX isohybrid MBR which makes the boot image
|
|
given by option -b bootable from USB sticks and hard disks via PC-BIOS.
|
|
This preparation is normally done by ISOLINUX program isohybrid
|
|
on the already produced ISO image.
|
|
@*
|
|
The disk path should lead to one of the Syslinux files isohdp[fp]x*.bin .
|
|
The MBR gets patched according to isohybrid needs. The first partition
|

describes the range of the ISO image. Its start is at block 0 by default,

@kindex -partition_offset Make mountable by partition 1

@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.

@item -partition_hd_cyl number

Set the number of sectors per head for the 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 allow exact alignment.
|
|
If it is too small to describe the image size by at most 1024 cylinders,
|
|
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. 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.

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.
|
|
@*
|
|
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
|
|
features, number 2 would be the most natural choice.

@*
|
|
If the use of libjte was enabled at compile time of xorriso, then

|
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:
|
|
@*
|
|

$ xorrisofs -version 2>&1 | grep '^libjte' && echo YES
|
|
@*
|
|
@sp 1
|
|
@c man .PP
|
|
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 xorrisofs session
|
|
with no image loaded, and a .md5 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 .md5 file by a single text line:
|
|
@*
|
|
MD5 as 32 hex digits, 2 blanks, size as 12 decimal digits or blanks, 2 blanks,
|
|
symbolic file address
|
|
@*
|
|
The file address in an .md5 line has to bear the same basename as the
|
|
disk_path of the file which it shall match. The directory path of
|
|
the file address is decisive for To=From mapping, not for file recognition.
|
|
After eventual To=From mapping, the file address gets written into the .jigdo
|
|
file. Jigdo restore tools will convert these addresses into really
|
|
reachable data source addresses from which they can read.

The first session is written like this:
|
|
@*
|
|
@sp 1
|
|
$ xorrisofs -graft-points \
|
|
@*
|
|

Follow-up sessions are written like this:
|
|
@*

@sp 1
|
|
$ m=$(xorriso -as cdrecord dev=/dev/sr0 -msinfo)
|
|
@*

|

@sp 1
|
|
Always eject the drive tray between sessions. The old sessions
|
|
get read via /dev/sr0. Its device driver might not be aware
|
|
of the changed content before it loads the media again.
|
|
@*
|
|
@sp 1
|
|
This example works for multi-session media only.
|
|
Add cdrskin option @minus{}@minus{}grow_overwriteable_iso

to all -as cdrecord runs
|
|
in order to enable multi-session emulation on overwriteable media.

@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{} outdev - -update_r /my/files /files
|
|
@*
|
|
$ growisofs -M /dev/dvd @minus{}@minus{} outdev - -update_r /my/files /files

@section Incremental backup of a few directory trees
|
|
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 expected that inode numbers in the disk filesystem are persistent
|
|
over cycles of mounting and booting.

Files with names matching *.o or *.swp get excluded explicitly.

To be used several times on the same media, whenever an update of

the old one.

This makes sense if the full backup leaves substantial remaining capacity

@strong{Better do not use your youngest backup for -old-root}.
|

Have at least two media which you use alternatingly. So only older backups
|
|
get endangered by the new write operation, while the newest backup is
|
|
stored safely on a different media.
|
|
Always have a blank media ready to perform a full backup in case the update

If inode numbers on disk are not persistent, then use

option @minus{}@minus{}old-root-no-ino .

With @strong{mount} option @strong{-o "sbsector="} on GNU/Linux
|
|
resp. @strong{-s} on FreeBSD
|
|
it is possible to access the session trees which represent the older backup
|
|
versions. With CD media, GNU/Linux mount accepts session numbers directly by
|
|
its option "session=".
|
|
@*
|
|
Multi-session media and most overwriteable 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
|
|
@*
|
|
@sp 1
|
|
Both yield on standard output something like:
|
|
@*
|
|
mount -t iso9660 -o nodev,noexec,nosuid,ro,sbsector=1460256 '/dev/sr0' '/mnt'
|
|
@*
|
|
@sp 1
|

The superuser may let xorriso execute the mount command directly:
|

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.
|

This demands to know the previously used session directory name.

|
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 parttion will start at hard disk block 64.
|
|
@*
|
|
@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

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 eventual 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

If not --no_rc is given as the first argument then xorrisofs
|
|
attempts on startup to read and execute lines from the following files:
|
|
@*
|
|
@sp 1
|
|
/etc/default/xorriso
|
|
@*
|
|
/etc/opt/xorriso/rc
|
|
@*
|
|
/etc/xorriso/xorriso.conf
|
|
@*
|
|
$HOME/.xorrisorc
|
|
@*
|
|
@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 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:
|
|
@*
|
|
@sp 1
|
|
./.mkisofsrc
|
|
@*
|
|
$MKISOFSRC
|
|
@*
|
|
$HOME/.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 reader currently interprets the following NAME=VALUE pairs:
|
|
@*
|
|
@sp 1
|
|
APPI default for -A
|
|
@*
|
|
PUBL default for -publisher
|
|
@*
|
|
SYSI default for -sysid
|
|
@*
|
|
VOLI default for -V
|
|
@*
|
|
VOLS default for -volset
|
|
@*
|
|
@sp 1
|
|
Any other lines will be silently ignored.
