Thanks, I'll look into that. For the moment I've just switched to having
an unencrypted root and encrypted /home partition (where the swapfile
also lives), which seems to me better from a security standpoint (I can
use --iter 500, sha512, &c. without an issue).

I mused briefly about mirroring of the relevant things (kernels, initrd)
from /gnu/store to /boot, but that's probably pretty hack-y.
