| 7 | Mount options that are the same as for msdos and vfat partitions. |

| 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. |

| 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 |
