UDF Filesystem version 0.9.8.1
|
|
|
|
If you encounter problems with reading UDF discs using this driver,
|
|
please report them to linux_udf@hpesjro.fc.hp.com, which is the
|
|
developer's list.
|
|
|
|
Write support requires a block driver which supports writing. The current
|
|
scsi and ide cdrom drivers do not support writing.
|
|
|
|
-------------------------------------------------------------------------------
|
|
The following mount options are supported:
|
|
|
|
gid= Set the default group.
|
|
umask= Set the default umask.
|
|
uid= Set the default user.
|
|
bs= Set the block size.
|
|
unhide Show otherwise hidden files.
|
|
undelete Show deleted files in lists.
|
|
adinicb Embed data in the inode (default)
|
|
noadinicb Don't embed data in the inode
|
|
shortad Use short ad's
|
|
longad Use long ad's (default)
|
|
nostrict Unset strict conformance
|
|
iocharset= Set the NLS character set
|
|
|
|
The uid= and gid= options need a bit more explaining. They will accept a
|
|
decimal numeric value which will be used as the default ID for that mount.
|
|
They will also accept the string "ignore" and "forget". For files on the disk
|
|
that are owned by nobody ( -1 ), they will instead look as if they are owned
|
|
by the default ID. The ignore option causes the default ID to override all
|
|
IDs on the disk, not just -1. The forget option causes all IDs to be written
|
|
to disk as -1, so when the media is later remounted, they will appear to be
|
|
owned by whatever default ID it is mounted with at that time.
|
|
|
|
For typical desktop use of removable media, you should set the ID to that
|
|
of the interactively logged on user, and also specify both the forget and
|
|
ignore options. This way the interactive user will always see the files
|
|
on the disk as belonging to him.
|
|
|
|
The remaining are for debugging and disaster recovery:
|
|
|
|
novrs Skip volume sequence recognition
|
|
|
|
The following expect a offset from 0.
|
|
|
|
session= Set the CDROM session (default= last session)
|
|
anchor= Override standard anchor location. (default= 256)
|
|
volume= Override the VolumeDesc location. (unused)
|
|
partition= Override the PartitionDesc location. (unused)
|
|
lastblock= Set the last block of the filesystem/
|
|
|
|
The following expect a offset from the partition root.
|
|
|
|
fileset= Override the fileset block location. (unused)
|
|
rootdir= Override the root directory location. (unused)
|
|
WARNING: overriding the rootdir to a non-directory may
|
|
yield highly unpredictable results.
