  Probably a bit of both :-)

  I would say this looks like a dracut problem: dracut is supposed to intall 
that file, but it doesn't seem to exist...

  Yann has been debugging a different dracut issue recently, perhaps he has some 
ideas on how to get better debugging info.

  dracut-install has --debug -and --logdir options, those may help.


  However, do these missing modules actually pose an issue? I think we get a 
bunch of error messages from dracut even in a known-to-be-working image. dracut 
is a bit of a mess.
