+[NOTE]
+squashfs-tools >=4.1-1 and/or squashfs-lzma-tools4 are the recommended package
+for building up2date ISOs with grml-live! Please use other squashfs-* packages
+only if you want to build live systems providing kernel versions older than
+2.6.35-grml*. Use squashfs-tools >=4.1-1 or squashfs-lzma-tools4 from Grml if
+you want to remaster any Grml releases MORE RECENT than 2010.04.
+
+Using squashfs-lzma-tools 4.0-2 on the build system
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+squashfs-lzma-tools 4.0-2 is available via the Grml repositories. It provides
+the mksquashfs-lzma and unsquashfs-lzma binaries. The package does NOT conflict
+with Debian's squashfs-tools package (you can install both of them at the same
+time).
+
+The packages can be downloaded from
+link:http://deb.grml.org/pool/main/s/squashfs-lzma-tools/[http://deb.grml.org/pool/main/s/squashfs-lzma-tools/]
+
+It provides support for the new squashfs file format version 4 (based on openwrt
+patches, this is *not* the mainline file format that's being used by kernel
+2.6.35-grml and squashfs-lzma-tools4!) and therefore requires kernel versions
+newer than 2.6.28-grml[64]. It supports LZMA as well as ZLIB compression. Just
+use the defaults for enabling LZMA or use grml-live's '-z' option if you want to
+use ZLIB instead.
+
+* Kernel \<=2.6.28-grml[64]: does not work
+* Kernel 2.6.31-grml[64]: works
+* Kernel 2.6.33-grml[64]: works
+* Kernel 2.6.35-grml[64]: works for ZLIB compression, fails for LZMA
+
+[NOTE]
+Please use squashfs-lzma-tools >=4.0-2 from Grml only if you want to remaster
+Grml releases 2009.10 and 2010.04 or live systems with their according kernel
+versions.
+
+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
+neither with the squashfs-lzma-tools 4.0-2 package nor with the
+squashfs-lzma-tools4 package (so you can install all 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 (dropped with
+link:http://packages.debian.org/changelogs/pool/main/s/squashfs-tools/current/changelog[version
+1:3.3-4] and not yet re-integrated yet, see
+link:http://bugs.debian.org/594595[#594595]). If you need LZMA support please
+use Grml's squashfs-lzma-tools[4] (see sections above) instead.
+
+* Kernels \<=2.6.28-grml[64]: does not work
+* Kernel 2.6.31-grml[64]: works (ZLIB only)
+* Kernel 2.6.33-grml[64]: works (ZLIB only)
+* Kernel 2.6.35-grml[64]: works (ZLIB only)
+* Kernel 2.6.36-grml[64]: works (ZLIB only)
+
+[NOTE]
+Please use squashfs-tools between 4.0-1 and 4.1-1 only if you want to remaster
+Grml releases starting with 2009.10 using the ZLIB compression, please use other
+squashfs packages otherwise instead.
+
+Outdated, JFTR:
+
+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.
+
+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 only if you want to remaster Grml releases
+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).
