I guess it's possible, but I haven't had time to test it out since I
don't know how to switch to it without doing a backup/restore cycle.

I'd also like to add an additional key to the home device so that if I
screw up my swap partition, the home partition is also not destroyed...
the output of 'cryptsetup luksDump' implies that this is possible but I
don't know if doing so will interfere with cryptsetup, etc.
