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.
