+Using squashfs-tools 1:4.0-X on the build system
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+squashfs-tools >=1:4.0-1 is available in Debian/unstable and Debian/testing. It
+provides the mksquashfs and unsquashfs binaries. The package does NOT
+conflict with the squashfs-lzma-tools 4.0-2 package (you can install both of
+them at the same time).
+
+The packages can be downloaded from
+link:ftp://ftp.de.debian.org/debian/pool/main/s/squashfs-tools/[ftp://ftp.de.debian.org/debian/pool/main/s/squashfs-tools/]
+
+It provides support for the new squashfs file format version 4 and therefore
+requires kernel versions newer than 2.6.28-grml[64].
+
+It does NOT support LZMA compression. If you need LZMA support please use
+Grml's squashfs-lzma-tools (see section above) instead.
+
+* Kernel 2.6.23-grml[64]: does not work
+* Kernel 2.6.26-grml[64]: does not work
+* Kernel 2.6.28-grml[64]: does not work
+* Kernel 2.6.31-grml[64]: works
+
+[NOTE]
+Please use squashfs-tools >=1:4.0-1 only if you want to remaster grml releases
+MORE RECENT than 2009.05 using the ZLIB compression.
+
+Using squashfs-lzma-tools 3.3-1 on the build system
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+squashfs-lzma-tools 3.3-1 from the grml repository supports kernel
+2.6.26-grml[64] and 2.6.28-grml[64] using both LZMA and ZLIB (-nolzma)
+compression. It's the recommended package for building ISOs with grml-live
+currently!
+
+The packages can be downloaded from
+link:http://deb.grml.org/pool/main/s/squashfs-lzma/[http://deb.grml.org/pool/main/s/squashfs-lzma/].
+
+[NOTE]
+Please use squashfs-lzma-tools 3.3-1 if you want to remaster grml release
+2008.11 or 2009.05.
+
+Using squashfs-tools 1:3.3-7 on the build system
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+squashfs-tools 1:3.3-7 is available through
+http://grml.org/squashfs/squashfs-tools_3.3-7_i386.deb (for x86) or
+http://grml.org/squashfs/squashfs-tools_3.3-7_amd64.deb (for amd64) [both build
+on and for Debian/etch but working with testing and unstable as well].
+
+Please notice that squashfs-tools 1:3.3-7 does NOT support LZMA compression at
+all (so you won't be able to remaster release 2008.11 and 2009.05 using LZMA for
+example). The -nolzma option of mksquashfs is not available therefore (even
+though grml-live will deactivate it for you automatically anyway). Please use
+squashfs-lzma-tools instead.
+
+* Kernel 2.6.23-grml: does NOT work, please use squashfs-tools 1:3.2r2-9exp1
+ instead if you still want to use kernel 2.6.23 (not
+ recommended)
+* Kernel 2.6.26-grml: works (without LZMA compression only of course!)
+* Kernel 2.6.28-grml: works (without LZMA compression only of course!)
+
+Using squashfs-tools 1:3.2r2-9exp1 on the build system
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+squashfs-tools 1:3.2r2-9exp1 is available via the grml-testing repository,
+running:
+
+ # aptitude install squashfs-tools=1:3.2r2-9exp1
+
+or directly via downloading the files
+http://grml.org/squashfs/squashfs-tools_3.2r2-9exp1_i386.deb (for x86) or
+http://grml.org/squashfs/squashfs-tools_3.2r2-9exp1_amd64.deb (for amd64).
+
+Using with ZLIB compression (SQUASHFS_OPTIONS='-nolzma' or -z
+option in grml-live cmdline):
+
+* Kernel 2.6.23-grml: works
+* Kernel 2.6.26-grml: works
+* Kernel 2.6.28-grml: supposed to work (not verified though)
+
+Using with LZMA compression:
+
+* Kernel 2.6.23-grml: works
+* Kernel 2.6.26-grml: does NOT work, please use ZLIB mode instead or switch
+ to Debian package squashfs-lzma-tools 3.3-1 (see section above).
+* Kernel 2.6.28-grml: does NOT work, please use ZLIB mode instead or switch
+ to Debian package squashfs-lzma-tools 3.3-1 (see section above).
