4 Macintosh HFSPlus Filesystem for Linux
5 ======================================
7 HFSPlus is a filesystem first introduced in MacOS 8.1.
8 HFSPlus has several extensions to HFS, including 32-bit allocation
9 blocks, 255-character unicode filenames, and file sizes of 2^63 bytes.
15 When mounting an HFSPlus filesystem, the following options are accepted:
17 creator=cccc, type=cccc
18 Specifies the creator/type values as shown by the MacOS finder
19 used for creating new files. Default values: '????'.
22 Specifies the user/group that owns all files on the filesystem
23 that have uninitialized permissions structures.
24 Default: user/group id of the mounting process.
27 Specifies the umask (in octal) used for files and directories
28 that have uninitialized permissions structures.
29 Default: umask of the mounting process.
32 Select the CDROM session to mount as HFSPlus filesystem. Defaults to
33 leaving that decision to the CDROM driver. This option will fail
34 with anything but a CDROM as underlying devices.
37 Select partition number n from the devices. This option only makes
38 sense for CDROMs because they can't be partitioned under Linux.
39 For disk devices the generic partition parsing code does this
40 for us. Defaults to not parsing the partition table at all.
43 Decompose file name characters.
46 Do not decompose file name characters.
49 Used to force write access to volumes that are marked as journalled
50 or locked. Use at your own risk.
53 Encoding to use when presenting file names.
