case={lower|asis}
           Convert all files names to lower case, or leave them. (Default:
           case=lower.)

       conv=mode
           This option is obsolete and may fail or being ignored.

       nocheck
           Do not abort mounting when certain consistency checks fail.

   Mount options for iso9660
       ISO 9660 is a standard describing a filesystem structure to be used on
       CD-ROMs. (This filesystem type is also seen on some DVDs. See also the
       udf filesystem.)

       Normal iso9660 filenames appear in an 8.3 format (i.e., DOS-like
       restrictions on filename length), and in addition all characters are in
       upper case. Also there is no field for file ownership, protection,
       number of links, provision for block/character devices, etc.

       Rock Ridge is an extension to iso9660 that provides all of these
       UNIX-like features. Basically there are extensions to each directory
       record that supply all of the additional information, and when Rock
       Ridge is in use, the filesystem is indistinguishable from a normal UNIX
       filesystem (except that it is read-only, of course).

       norock
           Disable the use of Rock Ridge extensions, even if available. Cf.
           map.

       nojoliet
           Disable the use of Microsoft Joliet extensions, even if available.
           Cf. map.

       check={r[elaxed]|s[trict]}
           With check=relaxed, a filename is first converted to lower case
           before doing the lookup. This is probably only meaningful together
           with norock and map=normal. (Default: check=strict.)

       uid=value and gid=value
           Give all files in the filesystem the indicated user or group id,
           possibly overriding the information found in the Rock Ridge
           extensions. (Default: uid=0,gid=0.)

       map={n[ormal]|o[ff]|a[corn]}
           For non-Rock Ridge volumes, normal name translation maps upper to
           lower case ASCII, drops a trailing ';1', and converts ';' to '.'.
           With map=off no name translation is done. See norock. (Default:
           map=normal.) map=acorn is like map=normal but also apply Acorn
           extensions if present.

       mode=value
           For non-Rock Ridge volumes, give all files the indicated mode.
           (Default: read and execute permission for everybody.) Octal mode
           values require a leading 0.

       unhide
           Also show hidden and associated files. (If the ordinary files and
           the associated or hidden files have the same filenames, this may
           make the ordinary files inaccessible.)

       block={512|1024|2048}
           Set the block size to the indicated value. (Default: block=1024.)

       conv=mode
           This option is obsolete and may fail or being ignored.

       cruft
           If the high byte of the file length contains other garbage, set this
           mount option to ignore the high order bits of the file length. This
           implies that a file cannot be larger than 16 MB.

       session=x
           Select number of session on a multisession CD.

       sbsector=xxx
           Session begins from sector xxx.

       The following options are the same as for vfat and specifying them only
       makes sense when using discs encoded using Microsoft’s Joliet
       extensions.

       iocharset=value
           Character set to use for converting 16 bit Unicode characters on CD
           to 8 bit characters. The default is iso8859-1.

       utf8
           Convert 16 bit Unicode characters on CD to UTF-8.

   Mount options for jfs
       iocharset=name
           Character set to use for converting from Unicode to ASCII. The
           default is to do no conversion. Use iocharset=utf8 for UTF8
           translations. This requires CONFIG_NLS_UTF8 to be set in the kernel
           .config file.

       resize=value
           Resize the volume to value blocks. JFS only supports
