| |
| 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. |
