That sounds very much like you just reinvented the wheel, since I can
do that already with opensuse's initrds. Perhaps not only that.
Everyone who packages GNU mount (which does in fact use blkid) has
the ability to mount by label, and Fedora is another one which can do
that. Plus, everyone should be supporting -b to start the emergency
shell. As far as switchroot is concerned, klibc provides run-init.
