+==================
+ISO9660 Filesystem
+==================
+
+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 UTF-8 translations with the
+ utf8 option.
+ utf8 Encode Unicode names in UTF-8 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 unless Rock Ridge
+ extensions set the permissions otherwise
+ dmode=xxx Sets the permissions on directories to xxx unless Rock Ridge
+ extensions set the permissions otherwise
+ overriderockperm Set permissions on files and directories according to
+ 'mode' and 'dmode' even though Rock Ridge extensions are
+ present.
+ 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

+identical with ISO 9660.", so it is a valid and gratis substitute of the
+official ISO specification.
