  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
  
  Recommended documents about ISO 9660 standard are located at:
  http://www.y-adagio.com/
  ftp://ftp.ecma.ch/ecma-st/Ecma-119.pdf
  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.
