Comment # 8 on bug 1189772 from Ludwig Nussel

/etc/sysconfig sucks that's true but so far we have no better way :-(

I don't really like the env var version as that would propagate to all users.

Dracut sources /etc/dracut.conf.d/* though and makes no assumption about the
valid keys in there. So you could just introduce settings similar to the ones
from initramfs-tools there.

For this specific case I really wonder why and initrd is built at all and what
from though. If there's no kernel package installed there's nothing to do!?
Also you could just rpm -e dracut, no?
