   4Macintosh HFSPlus Filesystem for Linux
   5======================================
   6
   7HFSPlus is a filesystem first introduced in MacOS 8.1.
   8HFSPlus has several extensions to HFS, including 32-bit allocation
   9blocks, 255-character unicode filenames, and file sizes of 2^63 bytes.

  12Mount options
  13=============
  14
  15When mounting an HFSPlus filesystem, the following options are accepted:
  16
  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: '????'.
  20
  21  uid=n, gid=n
  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.
  25
  26  umask=n
  27        Specifies the umask (in octal) used for files and directories
  28        that have uninitialized permissions structures.
  29        Default:  umask of the mounting process.
  30
  31  session=n
  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.
  35
  36  part=n
  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.
  41
  42  decompose
  43        Decompose file name characters.
  44
  45  nodecompose
  46        Do not decompose file name characters.
  47
  48  force
  49        Used to force write access to volumes that are marked as journalled
  50        or locked.  Use at your own risk.
  51
  52  nls=cccc
  53        Encoding to use when presenting file names.
