  13. ============== =============================================================
  14. iocharset=name Character set to use for converting from Unicode to
  15. ASCII. Joliet filenames are stored in Unicode format, but
  16. Unix for the most part doesn't know how to deal with Unicode.
  17. There is also an option of doing UTF-8 translations with the
  18. utf8 option.
  19. utf8 Encode Unicode names in UTF-8 format. Default is no.
  20. ============== =============================================================
  21. Mount options unique to the isofs filesystem.
  22. ================= ============================================================
  23. block=512 Set the block size for the disk to 512 bytes
  24. block=1024 Set the block size for the disk to 1024 bytes
  25. block=2048 Set the block size for the disk to 2048 bytes
  26. check=relaxed Matches filenames with different cases
  27. check=strict Matches only filenames with the exact same case
  28. cruft Try to handle badly formatted CDs.
  29. map=off Do not map non-Rock Ridge filenames to lower case
  30. map=normal Map non-Rock Ridge filenames to lower case
  31. map=acorn As map=normal but also apply Acorn extensions if present
  32. mode=xxx Sets the permissions on files to xxx unless Rock Ridge
  33. extensions set the permissions otherwise
  34. dmode=xxx Sets the permissions on directories to xxx unless Rock Ridge
  35. extensions set the permissions otherwise
  36. overriderockperm Set permissions on files and directories according to
  37. 'mode' and 'dmode' even though Rock Ridge extensions are
  38. present.
  39. nojoliet Ignore Joliet extensions if they are present.
  40. norock Ignore Rock Ridge extensions if they are present.
  41. hide Completely strip hidden files from the file system.
  42. showassoc Show files marked with the 'associated' bit
  43. unhide Deprecated; showing hidden files is now default;
  44. If given, it is a synonym for 'showassoc' which will
  45. recreate previous unhide behavior
  46. session=x Select number of session on multisession CD
  47. sbsector=xxx Session begins from sector xxx

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