\fB\-drive_class\fR "harmless"|"banned"|"caution"|"clear_list" disk_pattern
Add a drive path pattern to one of the safety lists or make those lists empty.
There are three lists defined which get tested in the following sequence:
.br
If a drive address path matches the "harmless" list then the drive will be
accepted. If it is not a MMC device then the prefix "stdio:" will be prepended
automatically. This list is empty by default.
.br
Else if the path matches the "banned" list then the drive will not be
accepted by \fBxorriso\fR but rather lead to a FAILURE event.
This list is empty by default.
.br
Else if the path matches the "caution" list and if it is not a MMC device,
then its address must have the prefix "stdio:" or it will be rejected.
This list has by default one entry: "/dev".
.br
If a drive path matches no list then it is considered "harmless". By default
these are all paths which do not begin with directory "/dev".
.br
A path matches a list if one of its parent paths or itself matches a list
entry. Address prefix "stdio:" or "mmc:" will be ignored when
testing for matches.
.br
By pseudo\-class "clear_list" and pseudo\-patterns "banned", "caution",
"harmless", or "all", the lists may be made empty.

\fB\-drive_access\fR "exclusive"|"shared":"unrestricted"|"readonly"
Control whether device file locking mechanisms shall be used when acquiring a
drive, and whether status or content of the medium in the drive may be
altered. Useful and most harmless are the setting "shared:readonly"
and the default setting "exclusive:unrestricted".
.br
"exclusive" enables tests and locks when acquiring the drive. It depends on the
operating system which locking mechanisms get applied, if any. On GNU/Linux
it is open(O_EXCL). On FreeBSD it is flock(LOCK_EX).
.br
"shared" disables the use of these mechanisms to become able to acquire drives
which are mounted, or opened by some process, or guarded by /dev/pktcdvd*.
.br
"unrestricted" enables all technically appropriate operations on an acquired
drive. "shared:unrestricted" risks to get own burn runs spoiled by other
processes or to vice versa spoil activities of such processes. So use
"exclusive:unrestricted" unless you know for sure that "shared" is safe.
.br
"readonly" disables operations which might surprise a co\-user of the drive.
For \-outdev these are formatting, blanking, writing, ejecting. For \-indev
this is ejecting. Be aware that even reading and drive status inquiries can
disturb an ongoing burn run on CD\-R[W] and DVD\-R[W].

@kindex -drive_class controls drive accessability
@cindex Drive, accessability, -drive_class
Add a drive path pattern to one of the safety lists or make those lists empty.
There are three lists defined which get tested in the following sequence:
@*
If a drive address path matches the "harmless" list then the drive will be
accepted. If it is not a MMC device then the prefix "stdio:" will be prepended
automatically. This list is empty by default.
@*
Else if the path matches the "banned" list then the drive will not be
accepted by @command{xorriso} but rather lead to a FAILURE event.
This list is empty by default.
@*
Else if the path matches the "caution" list and if it is not a MMC device,
then its address must have the prefix "stdio:" or it will be rejected.
This list has by default one entry: "/dev".
@*
If a drive path matches no list then it is considered "harmless". By default
these are all paths which do not begin with directory "/dev".
@*
A path matches a list if one of its parent paths or itself matches a list
entry. Address prefix "stdio:" or "mmc:" will be ignored when
testing for matches.
@*
By pseudo-class "clear_list" and pseudo-patterns "banned", "caution",
"harmless", or "all", the lists may be made empty.
@*
E.g.: -drive_class clear_list banned
@*
One will normally define the -drive_class lists in one of the @command{xorriso}
Startup Files.
@*
Note: This is not a security feature but rather a bumper for the superuser to
prevent inadverted mishaps. For reliably blocking access to a device file you
have to deny its rw-permissions in the filesystem.
@c man .TP
@item -drive_access "exclusive"|"shared":"unrestricted"|"readonly"
@kindex -drive_access control device file locking
@cindex Device file locking, -drive_access
Control whether device file locking mechanisms shall be used when acquiring a
drive, and whether status or content of the medium in the drive may be
altered. Useful and most harmless are the setting "shared:readonly"
and the default setting "exclusive:unrestricted".
@*
"exclusive" enables tests and locks when acquiring the drive. It depends on the
operating system which locking mechanisms get applied, if any. On GNU/Linux
it is open(O_EXCL). On FreeBSD it is flock(LOCK_EX).
@*
"shared" disables the use of these mechanisms to become able to acquire drives
which are mounted, or opened by some process, or guarded by /dev/pktcdvd*.
@*
"unrestricted" enables all technically appropriate operations on an acquired
drive. "shared:unrestricted" risks to get own burn runs spoiled by other
processes or to vice versa spoil activities of such processes. So use
"exclusive:unrestricted" unless you know for sure that "shared" is safe.
@*
"readonly" disables operations which might surprise a co-user of the drive.
For -outdev these are formatting, blanking, writing, ejecting. For -indev
this is ejecting. Be aware that even reading and drive status inquiries can
disturb an ongoing burn run on CD-R[W] and DVD-R[W].

Else if the path matches the "caution" list and if it is not a MMC device,
then its address must have the prefix "stdio:" or it will be rejected.
This list has by default one entry: "/dev".

If a drive path matches no list then it is considered "harmless". By default
these are all paths which do not begin with directory "/dev".

A path matches a list if one of its parent paths or itself matches a list
entry. Address prefix "stdio:" or "mmc:" will be ignored when
testing for matches.

By pseudo-class "clear_list" and pseudo-patterns "banned", "caution",
"harmless", or "all", the lists may be made empty.

One will normally define the -drive_class lists in one of the @command{xorriso}

Note: This is not a security feature but rather a bumper for the superuser to
prevent inadverted mishaps. For reliably blocking access to a device file you
have to deny its rw-permissions in the filesystem.

Option "o_excl_on" is the default unless the program was started with leafname

use by other libburn programs.
