Current kernel.spec runs dracut in %posttrans, probably exactly to make
sure it only runs after everything is actually installed.

Ok.

Hmm, that is somehow the wrong direction.  IMHO we should fix package
dependencies (assuming this is a problem still) to make sure the initrd
is always generated correctly during package installation instead of
having anaconda workaround broken dependencies.
