Kernel 2.6.38-grml available
Only two days after Linus released Kernel 2.6.38 we already have it in the grml-testing repository! Besides the usual AUFS support it also features mainline’s squashfs XZ support, meaning no extra squashfs patch needed anymore to get support for LZMA (now known as XZ). Our build tool grml-live(8) already supports this kernel version and uses XZ compression with squashfs-tools >=1:4.2-1 by default. Please note: If you want to use current grml-live version (>=0.13.1) with older kernel versions than 2.6.38 don’t forget to point SQUASHFS_BINARY to the according mksquashfs binary and set SQUASHFS_OPTIONS accordingly. If you want to build older versions without any hassles you can still use old grml-live versions of course (as provided and shipped with each Grml release). Bottom line, XZ support in mainline (kernel >=2.6.38 and squashfs-tools >=4.2) will provide a better upgrade cycle for grml-live and the grml environment.
