One possible improvement (not for this patch but long term) is to use
initramfs-framework for this. It provides a modular system and has
some nice featues for debug and shell handling so you can say:

debug=before:udev shell=after:e2fs

Just an example. Another good thing about it is it allow for less code
duplication.
