[Fedora-livecd-list] lzma + squashfs should be easy to use in livecd-tools

Phillip Lougher posted lmza+squashfs patches to lkml yesterday and today as a followup he posted a message indicating how to build / use the new sqaushfs-tools to build or read squashfs file systems. (http://marc.info/?l=linux-embedded&m=126029628723357&w=2) The short description is that to use lzma compression when building squashfs images you add a -comp lzma option and that when reading squashfs file systems the type of compression is automatically detected and no special action is needed. If it is desired to have a single version of livecd-creator that works regardless of whether or not mksquashfs supports lzma, it is possible to run mksquashfs without any arguments and examine the output to see if lzma is supported. It may also be necessary to check for a minimum kernel being used for livecd image if livecd-creator is supposed to be able to compose older versions of Fedora. While I don't think I'd call this a "feature", I'd like to have something testable by feature freeze and am willing to do some work to make this happen.
