To make it easier to track problems this section documents current state of
grml-live playing together with squashfs-tools / squashfs-lzma-tools (for
building the compressed file) and the kernel version. Documentation of this

Difference between squashfs-lzma-tools and squashfs-tools
Squashfs-tools was introduced in Debian and once provided support for LZMA
compression. Sadly LZMA compression within squashfs-tools became unsupported and
-therefore squashfs-lzma-tools had to be introduced. Different kernel versions
-provide different squashfs file formats (version 3.x for kernel versions until
-2.6.28-grml[64], newer kernel versions use the 4.x format).
+therefore squashfs-lzma-tools had to be introduced by the Grml team. Different
+kernel versions provide different squashfs file formats (version 3.x for kernel
+versions until 2.6.28-grml[64], since kernel 2.6.31-grml[64] it's the 4.x
+format).

+If you're wondering which package supports what, here's a short overview:
* squashfs-tools 1:4.0-1: ZLIB as default, no LZMA support/options, file format
version 4
* squashfs-tools 1:3.2r2-9exp1: LZMA as default, ZLIB support via -nolzma
option, file format version 3
+* squashfs-lzma-tools 4.0-1: LZMA as default, no ZLIB support/options, file format 4

file format version 3
-* squashfs-lzma-tools 4.0-1: LZMA as default, no ZLIB support/options, file format 4

Depending on the kernel version you want to use you need different versions
squashfs-tools/squashfs-lzma-tools. Yes, that's pretty a mess (don't ask how
much this sucks for us developers) - though this is supposed to calm down with
the recent integration of squashfs file format 4 in the mainline kernel. Support
for LZMA is pending and should dramatically simplify the situation for
-developers as well as users.
