My drivers are compiled into my kernel, and the kernel is on the same
drive (though a different partition) as the one that's going to be
cryptsetup'd. Things work super well and super simply. It's very
minimal. As far as I can see with my particular setup, there are no
potential races either. Cryptsetup itself works fine without the udev
hooks, as the mapped device node is created before luksOpen exits.
