Hmm, that doesn't play too well with plymouth, too, it gets stuck in a text
mode screen and you can't quit it either. Too bad folks didn't think of a
good way to control these tools when GUI isn't working. Doesn't it have any
keyboard shortcuts?

Shouldn't "text nosplash" options be sufficient? They don't seem to work for
me however, is there a way to give a plymouth option, there was
plymouth:debug so maybe there is something else, too? I'm just trying to get
a nice clean text login. Used to be easier with debian/FAI. I still haven't
checked if ssh works all right, but network does work so it shouldn't be a
problem.

Oh, you should try my dracut patch I suppose, I'll make it available in
short order.
