I want to reinstall fedora on a intel fake-raid1 which is practically
a software raid. In order to save all the config headaches I want to
use a f16-livecd and rebuild the netinstall image with the kernel for
f15 (kernel-2.6.40.4-6.fc15) and just boot from it. So from your
example '# dracut initrd.img `uname -r' I think `uname -r` will return
the running f16 kernel, not the one I want to use. Do I need the
kernel-devel-package for this?
