    $ cat /usr/lib/dracut/dracut.conf.d/*.conf

Our default settings for dracut doesn't include multipath and dmraid.
We haven't shipped multipathd, anyway.
The dracut.spec file also put kpartx in the Recommends for fedora and
rhel (or for anything not fedora and rhel, I'm not familiar with spec
grmmar).

But, I think adding kpartx isn't a big deal, since it's a tiny package.

But, if we're gonna add every binary that dracut is using to depends,
I don't think it's a good idea.

How about adding this patch instead:
