| 7 | Mount options that are the same as for msdos and vfat partitions. | |
| 8 | ||
| 9 | ========= ======================================================== | |
| 10 | gid=nnn All files in the partition will be in group nnn. | |
| 11 | uid=nnn All files in the partition will be owned by user id nnn. | |
| 12 | umask=nnn The permission mask (see umask(1)) for the partition. | |
| 13 | ========= ======================================================== | |

| 15 | Mount options that are the same as vfat partitions. These are only useful | |
| 16 | when using discs encoded using Microsoft's Joliet extensions. | |
| 17 | ||
| 18 | ============== ============================================================= | |
| 19 | iocharset=name Character set to use for converting from Unicode to | |
| 20 | ASCII. Joliet filenames are stored in Unicode format, but | |
| 21 | Unix for the most part doesn't know how to deal with Unicode. | |
| 22 | There is also an option of doing UTF-8 translations with the | |
| 23 | utf8 option. | |
| 24 | utf8 Encode Unicode names in UTF-8 format. Default is no. | |
| 25 | ============== ============================================================= | |
| 26 | ||
| 27 | Mount options unique to the isofs filesystem. | |
| 28 | ||
| 29 | ================= ============================================================ | |
| 30 | block=512 Set the block size for the disk to 512 bytes | |
| 31 | block=1024 Set the block size for the disk to 1024 bytes | |
| 32 | block=2048 Set the block size for the disk to 2048 bytes | |
| 33 | check=relaxed Matches filenames with different cases | |
| 34 | check=strict Matches only filenames with the exact same case | |
| 35 | cruft Try to handle badly formatted CDs. | |
| 36 | map=off Do not map non-Rock Ridge filenames to lower case | |
| 37 | map=normal Map non-Rock Ridge filenames to lower case | |
| 38 | map=acorn As map=normal but also apply Acorn extensions if present | |
| 39 | mode=xxx Sets the permissions on files to xxx unless Rock Ridge | |
| 40 | extensions set the permissions otherwise | |
| 41 | dmode=xxx Sets the permissions on directories to xxx unless Rock Ridge | |
| 42 | extensions set the permissions otherwise | |
| 43 | overriderockperm Set permissions on files and directories according to | |
| 44 | 'mode' and 'dmode' even though Rock Ridge extensions are | |
| 45 | present. | |
| 46 | nojoliet Ignore Joliet extensions if they are present. | |
| 47 | norock Ignore Rock Ridge extensions if they are present. | |
| 48 | hide Completely strip hidden files from the file system. | |
| 49 | showassoc Show files marked with the 'associated' bit | |
| 50 | unhide Deprecated; showing hidden files is now default; | |
| 51 | If given, it is a synonym for 'showassoc' which will | |
| 52 | recreate previous unhide behavior | |
| 53 | session=x Select number of session on multisession CD | |
| 54 | sbsector=xxx Session begins from sector xxx | |

| 63 | identical with ISO 9660.", so it is a valid and gratis substitute of the | |
