This is related to this message I posted yesterday: http://www.redhat.com/archives/libguestfs/2010-January/msg00016.html fakechroot doesn't sufficiently contain dracut, which is what was very indirectly causing that problem. However we don't need to run /sbin/new-kernel-package (in the kernel %post script). It takes a long time because dracut is so slow, and it builds an initrd that we never use. So the easiest thing here is to disable this (and also nscd which some %post scripts are trying to run).
