SQUASHFS 4.0 - A squashed read-only filesystem for Linux
|
||
|
|
|
||
|

Copyright 2002-2009 Phillip Lougher <phillip@lougher.demon.co.uk>

|
|
Released under the GPL licence (version 2 or later).
|
||
|
|
|
||
|
|
Welcome to Squashfs 4.0. This is an initial tools only release to
|
||
|
|
support users of the 2.6.29 kernel, following the mainlining of Squashfs
|
||
|
|
earlier this year.
|
||
|
|
|
||
|
|
Later releases will probably contain kernel patches supporting 4.0
|
||
|
|
layouts for earlier kernels.
|
||
|

||
|
|
New Mksquashfs options
|
||
|
|
----------------------
|
||
|
|
|
||
|
|
Mksquashfs now supports pseudo files, these allow fake directories, character
|
||
|
|
and block devices to be specified and added to the Squashfs filesystem being
|
||
|
|
built, rather than requiring them to be present in the source directories.
|
||
|
|
This, for example, allows device nodes to be added to the filesystem without
|
||
|
|
requiring root access.
|
||
|
|
|
||
|
|
Two options are supported, -p allows one pseudo file to be specified on the
|
||
|
|
command line, and -pf allows a pseudo file to be specified containing a
|
||
|
|
list of pseduo definitions, one per line.
|
||
|
|
|
||
|
|
Pseudo device nodes are specified using 7 arguments
|
||
|
|
|
||
|
|
Filename type mode uid gid major minor
|
||
|
|
|
||
|
|
Where type is either
|
||
|
|
b - for block devices, and
|
||
|
|
c - for character devices
|
||
|
|
|
||
|
|
mode is the octal mode specifier, similar to that expected by chmod.
|
||
|
|
|
||
|
|
Uid and gid can be either specified as a decimal number, or by name.
|
||
|
|
|
||
|
|
For example:
|
||
|
|
|
||
|
|
/dev/chr_dev c 666 root root 100 1
|
||
|
|
/dev/blk_dev b 444 0 0 200 200
|
||
|
|
|
||
|
|
Directories are specified using 5 arguments
|
||
|
|
|
||
|
|
Filename type mode uid gid
|
||
|
|
|
||
|
|
Where type is d.
