Description: build system for creating a Grml (based) Linux live system
Current state of grml-live with squashfs-tools and kernel
---------------------------------------------------------
-To make it easier to track problems this section documents current state of
-grml-live playing together with squashfs-tools / squashfs-lzma-tools /
-squashfs-lzma-tools4 (for building the compressed file) and the kernel version.
-Documentation of this section is up2date by 1st of september 2010, please report
-any bugs you encounter.
+Use squashfs-tools >=4.1-1 (available from Grml repositories as well as from
+Debian/experimental) to build Grml (based) ISOs featuring kernel version
+2.6.36-grml[64].
+////////////////////////////////////////////////////////////////////////////////
Difference between squashfs-lzma-tools, squashfs-lzma-tools4 and squashfs-tools
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
version 4, package maintained and available from Debian, recommended only for
ZLIB-only builds of any grml-live builds with kernel versions >=2.6.31-grml[64]
-////////////////////////////////////////////////////////////////////////////////
Outdated, JFTR:
* squashfs-tools 1:3.3-7: ZLIB as default, no LZMA support/options, file format
* squashfs-lzma-tools 3.3-1: LZMA as default, ZLIB support via '-nolzma' option,
file format version 3
-////////////////////////////////////////////////////////////////////////////////
Now, depending on the kernel version you want to use you need different versions
of squashfs-tools/squashfs-lzma-tools[4]. Yes, that's a mess (don't ask how much
* Kernel 2.6.31-grml[64]: works with ZLIB compression, fails with LZMA
* Kernel 2.6.33-grml[64]: works with ZLIB compression, fails with LZMA
* Kernel 2.6.35-grml[64]: works with ZLIB *and* LZMA compression
+* Kernel 2.6.36-grml[64]: works with ZLIB *and* LZMA compression
[NOTE]
-squashfs-lzma-tools4 is 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-lzma-tools4 from Grml if you want to remaster any Grml releases MORE
-RECENT than 2010.04.
+squashfs-tools >=4.1-1 and/or squashfs-lzma-tools4 are the recommended package

Using squashfs-lzma-tools 4.0-2 on the build system
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

* Kernel 2.6.35-grml[64]: works (ZLIB only)
+* Kernel 2.6.36-grml[64]: works (ZLIB only)
[NOTE]
-Please use squashfs-tools >=1:4.0-1 only if you want to remaster Grml releases
-starting with 2009.10 using the ZLIB compression, please use squashfs-lzma-tools
-/ squashfs-lzma-tools4 otherwise instead.
+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
