the fedora template works for 14 but not 15
the reason is systemd but not really related to rc.sysinit (yes this
needs cleanup)
systemd in the container seems to interfere with systemd on the host
screwing up the host
i haven't been looking at it lately, but i think it might be related
to mount points or something
as systemd uses /var/run/ which is a tmpfs, som maybe something goes wrong there
