ian@0 4 UDF Filesystem version 0.9.8.1
ian@0 5
ian@0 6 If you encounter problems with reading UDF discs using this driver,
ian@0 7 please report them to linux_udf@hpesjro.fc.hp.com, which is the
ian@0 8 developer's list.
ian@0 9
ian@0 10 Write support requires a block driver which supports writing. The current
ian@0 11 scsi and ide cdrom drivers do not support writing.
ian@0 12
ian@0 13 -------------------------------------------------------------------------------
ian@0 14 The following mount options are supported:
ian@0 15
ian@0 16 gid= Set the default group.
ian@0 17 umask= Set the default umask.
ian@0 18 uid= Set the default user.
ian@0 19 bs= Set the block size.
ian@0 20 unhide Show otherwise hidden files.
ian@0 21 undelete Show deleted files in lists.
ian@0 22 adinicb Embed data in the inode (default)
ian@0 23 noadinicb Don't embed data in the inode
ian@0 24 shortad Use short ad's
ian@0 25 longad Use long ad's (default)
ian@0 26 nostrict Unset strict conformance
ian@0 27 iocharset= Set the NLS character set
ian@0 28
ian@0 29 The uid= and gid= options need a bit more explaining. They will accept a
ian@0 30 decimal numeric value which will be used as the default ID for that mount.
ian@0 31 They will also accept the string "ignore" and "forget". For files on the disk
ian@0 32 that are owned by nobody ( -1 ), they will instead look as if they are owned
ian@0 33 by the default ID. The ignore option causes the default ID to override all
ian@0 34 IDs on the disk, not just -1. The forget option causes all IDs to be written
ian@0 35 to disk as -1, so when the media is later remounted, they will appear to be
ian@0 36 owned by whatever default ID it is mounted with at that time.
ian@0 37
ian@0 38 For typical desktop use of removable media, you should set the ID to that
ian@0 39 of the interactively logged on user, and also specify both the forget and
ian@0 40 ignore options. This way the interactive user will always see the files
ian@0 41 on the disk as belonging to him.
ian@0 42
ian@0 43 The remaining are for debugging and disaster recovery:
ian@0 44
ian@0 45 novrs Skip volume sequence recognition
ian@0 46
ian@0 47 The following expect a offset from 0.
ian@0 48
ian@0 49 session= Set the CDROM session (default= last session)
ian@0 50 anchor= Override standard anchor location. (default= 256)
ian@0 51 volume= Override the VolumeDesc location. (unused)
ian@0 52 partition= Override the PartitionDesc location. (unused)
ian@0 53 lastblock= Set the last block of the filesystem/
ian@0 54
ian@0 55 The following expect a offset from the partition root.
ian@0 56
ian@0 57 fileset= Override the fileset block location. (unused)
ian@0 58 rootdir= Override the root directory location. (unused)
ian@0 59 WARNING: overriding the rootdir to a non-directory may
ian@0 60 yield highly unpredictable results.
