Hmm. So I pulled, because I think it is the right thing in the long
run. But right now I'm bisecting a non-booting machine, and it seems
to be due to the workqueue pull.

It's not fully bisected yet, but the only remaining thing I actually
enable is workqueues. The symptom is a machine that stops at

  ...
  dracut: Starting plymouth daemon
  dracut: Scanning devices sda2  for LVM volume groups
  dracut: Reading all physical volumes. This may take a while...
  dracut: Found volume group "VolGroup" using metadata type lvm2

and the next thing I'd expect to see is the mounting of the filesystem
and the SElinux notifications. And I never do.

I'll bisect it all the way, but thought I'd let you know.
