   7 Welcome to Squashfs 4.0.  This is an initial tools only release to
   8 support users of the 2.6.29 kernel, following the mainlining of Squashfs
   9 earlier this year.
  10
  11 Later releases will probably contain kernel patches supporting 4.0
  12 layouts for earlier kernels.

  14 New Mksquashfs options
  15 ----------------------
  16
  17 Mksquashfs now supports pseudo files, these allow fake directories, character
  18 and block devices to be specified and added to the Squashfs filesystem being
  19 built, rather than requiring them to be present in the source directories.
  20 This, for example, allows device nodes to be added to the filesystem without
  21 requiring root access.
  22
  23 Two options are supported, -p allows one pseudo file to be specified on the
  24 command line, and -pf allows a pseudo file to be specified containing a
  25 list of pseduo definitions, one per line.
  26
  27 Pseudo device nodes are specified using 7 arguments
  28
  29 Filename type mode uid gid major minor
  30
  31 Where type is either
  32         b - for block devices, and
  33         c - for character devices
  34
  35 mode is the octal mode specifier, similar to that expected by chmod.
  36
  37 Uid and gid can be either specified as a decimal number, or by name.
  38
  39 For example:
  40
  41 /dev/chr_dev c 666 root root 100 1
  42 /dev/blk_dev b 444 0 0 200 200
  43
  44 Directories are specified using 5 arguments
  45
  46 Filename type mode uid gid
  47
  48 Where type is d.
