2Macintosh HFSPlus Filesystem for Linux
3======================================
4
5HFSPlus is a filesystem first introduced in MacOS 8.1.
6HFSPlus has several extensions to HFS, including 32-bit allocation
7blocks, 255-character unicode filenames, and file sizes of 2^63 bytes.

10Mount options
11=============
12
13When mounting an HFSPlus filesystem, the following options are accepted:
14
15 creator=cccc, type=cccc
16 Specifies the creator/type values as shown by the MacOS finder
17 used for creating new files. Default values: '????'.
18
19 uid=n, gid=n
20 Specifies the user/group that owns all files on the filesystem
21 that have uninitialized permissions structures.
22 Default: user/group id of the mounting process.
23
24 umask=n
25 Specifies the umask (in octal) used for files and directories
26 that have uninitialized permissions structures.
27 Default: umask of the mounting process.
28
29 session=n
30 Select the CDROM session to mount as HFSPlus filesystem. Defaults to
31 leaving that decision to the CDROM driver. This option will fail
32 with anything but a CDROM as underlying devices.
33
34 part=n
35 Select partition number n from the devices. This option only makes
36 sense for CDROMs because they can't be partitioned under Linux.
37 For disk devices the generic partition parsing code does this
38 for us. Defaults to not parsing the partition table at all.
39
40 decompose
41 Decompose file name characters.
42
43 nodecompose
44 Do not decompose file name characters.
45
46 force
47 Used to force write access to volumes that are marked as journalled
48 or locked. Use at your own risk.
49
50 nls=cccc
51 Encoding to use when presenting file names.
