   6
   7Mount options that are the same as vfat partitions. These are only useful
   8when using discs encoded using Microsoft's Joliet extensions.
   9  iocharset=name Character set to use for converting from Unicode to
  10                ASCII.  Joliet filenames are stored in Unicode format, but
  11                Unix for the most part doesn't know how to deal with Unicode.
  12                There is also an option of doing UTF-8 translations with the
  13                utf8 option.
  14  utf8          Encode Unicode names in UTF-8 format. Default is no.

  16Mount options unique to the isofs filesystem.
  17  block=512     Set the block size for the disk to 512 bytes
  18  block=1024    Set the block size for the disk to 1024 bytes
  19  block=2048    Set the block size for the disk to 2048 bytes
  20  check=relaxed Matches filenames with different cases
  21  check=strict  Matches only filenames with the exact same case
  22  cruft         Try to handle badly formatted CDs.
  23  map=off       Do not map non-Rock Ridge filenames to lower case
  24  map=normal    Map non-Rock Ridge filenames to lower case
  25  map=acorn     As map=normal but also apply Acorn extensions if present
  26  mode=xxx      Sets the permissions on files to xxx unless Rock Ridge
  27                extensions set the permissions otherwise
  28  dmode=xxx     Sets the permissions on directories to xxx unless Rock Ridge
  29                extensions set the permissions otherwise
  30  overriderockperm Set permissions on files and directories according to
  31                'mode' and 'dmode' even though Rock Ridge extensions are
  32                present.
  33  nojoliet      Ignore Joliet extensions if they are present.
  34  norock        Ignore Rock Ridge extensions if they are present.
  35  hide          Completely strip hidden files from the file system.
  36  showassoc     Show files marked with the 'associated' bit
  37  unhide        Deprecated; showing hidden files is now default;
  38                If given, it is a synonym for 'showassoc' which will
  39                recreate previous unhide behavior
  40  session=x     Select number of session on multisession CD
  41  sbsector=xxx  Session begins from sector xxx

  43Recommended documents about ISO 9660 standard are located at:
  44http://www.y-adagio.com/
  45ftp://ftp.ecma.ch/ecma-st/Ecma-119.pdf
  46Quoting from the PDF "This 2nd Edition of Standard ECMA-119 is technically 
  47identical with ISO 9660.", so it is a valid and gratis substitute of the
  48official ISO specification.
