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 | |
64 | official ISO specification. |
