JFYI: We (the grml team) have working squashfs 4 + lzma patches for
kernel 2.6.31 and an according squashfs-tools package providing
lzma support. Please let me know if we can assist in any way.
I believe these patches are based on the OpenWRT Squashfs patches.
In that case I strongly advise against using them in Debian.
The Squashfs 4.0 LZMA filesystems generated by the OpenWRT patches
are incompatible with my 'official' Squashfs LZMA 4.0 filesystems
and will not (and cannot, see below) be officially supported.
While is OK for an embedded system to use incompatible Squashfs
versions (they can just regenerate the filesystem), it is unwise
for a distribution because users will find they cannot read
their LZMA compressed 4.0 filesystems in the future.
