Rawhide has xz-compressed kernel modules. I think this is a good thing as it saves a lot of disk space in VMs. It did however necessitate a change in supermin (used by libguestfs). Upstream already supported xz-compressed modules -- the patch was contributed by Arch Linux which has been using them for a long time. However it was not turned on in Fedora because it needs a statically linked liblzma (we're building a tiny, static init to bootstrap a VM). So I've taken co-maint of xz and added the xz-static subpackage. [Discussion: https://bugzilla.redhat.com/show_bug.cgi?id=547011 ] I've added this to Rawhide. It's waiting in updates-testing for F20, and could do with some testing and karma: https://admin.fedoraproject.org/updates/FEDORA-2014-6534/xz-5.1.2-9alpha.fc20,supermin-5.1.8-5.fc20 I've not done anything for F19. Please let me know if xz-compressed modules will be turned on there.
