The current isofs treatment of hidden files is flawed in two ways. First, it does not provide sufficient granularity; it hides both 'hidden' files and 'associated' files (resource fork for Mac files). Second, the default behavior to completely strip hidden files, while an admirable implementation of the spec, is a poor choice given the real world use of hidden files as a poor mans copy protection scheme for MSDOS and Windows based systems. A longer description of this is available here: http://www.uwsg.iu.edu/hypermail/linux/kernel/0205.3/0267.html This patch was originally built after a few private conversations with Alan Cox; I shamefully failed to persist in seeing it go forward, I hope to make amends now. This patch introduces granularity by allowing explicit control for both hidden and associated files. It also reverses the default so that by default, hidden files are treated as regular files on the iso9660 file system. This allow Wine to process Windows CDs, including those that are hybrid Mac/Windows CDs properly and completely, without our having to go muck up peoples fstabs as we do now. (I have tested this with such a hybrid + hidden CD and have verified that this patch works as claimed).

Mount options that are the same as for msdos and vfat partitions.
|
|
|
|
gid=nnn All files in the partition will be in group nnn.
|
|
uid=nnn All files in the partition will be owned by user id nnn.
|
|
umask=nnn The permission mask (see umask(1)) for the partition.
|
|
|
|
Mount options that are the same as vfat partitions. These are only useful
|
|
when using discs encoded using Microsoft's Joliet extensions.
|
|
iocharset=name Character set to use for converting from Unicode to
|
|
ASCII. Joliet filenames are stored in Unicode format, but
|
|
Unix for the most part doesn't know how to deal with Unicode.
|
|
There is also an option of doing UTF8 translations with the
|
|
utf8 option.
|
|
utf8 Encode Unicode names in UTF8 format. Default is no.
|
|
|
|
Mount options unique to the isofs filesystem.
|
|
block=512 Set the block size for the disk to 512 bytes
|
|
block=1024 Set the block size for the disk to 1024 bytes
|
|
block=2048 Set the block size for the disk to 2048 bytes
|
|
check=relaxed Matches filenames with different cases
|
|
check=strict Matches only filenames with the exact same case
|
|
cruft Try to handle badly formatted CDs.
|
|
map=off Do not map non-Rock Ridge filenames to lower case
|
|
map=normal Map non-Rock Ridge filenames to lower case
|
|
map=acorn As map=normal but also apply Acorn extensions if present
|
|
mode=xxx Sets the permissions on files to xxx
|
|
nojoliet Ignore Joliet extensions if they are present.
|
|
norock Ignore Rock Ridge extensions if they are present.
|
|
hide Completely strip hidden files from the file system.
|
|
showassoc Show files marked with the 'associated' bit
|
|
unhide Deprecated; showing hidden files is now default;
|
|
If given, it is a synonym for 'showassoc' which will
|
|
recreate previous unhide behavior
|
|
session=x Select number of session on multisession CD
|
|
sbsector=xxx Session begins from sector xxx
|

Quoting from the PDF "This 2nd Edition of Standard ECMA-119 is technically
|
|
identical with ISO 9660.", so it is a valid and gratis substitute of the
|
|
official ISO specification.
