I suspect the issue is dracut_install calling with null strings .... but I can't begin to explain what causes that.

confirmed and fixed at upstream, v049 contains the fix https://git.kernel.org/pub/scm/boot/dracut/dracut.git/commit/?id=e331e06a3910ef3fe6837f3e93a48123a7cc822b
I can confirm that applying this patch only over 048-r1 fixes the issue. So can at least a 048-r2 be released, if not 049?
