It is, and I don't know, but that's the way the dist is set up
and not under my control.

I'm trying to figure out how to do it "right", ie something that
will work with standard debian. I have an entry /dev/swap0 in
/etc/fstab that I soft link to either /dev/loop6 is the kernel
which is booting has loop back; or to the actual device partition
otherwise. That handles the problem switching kernels. If I
do it after checkroot, the swap has been activated. I'm trying
to slip in and make the debian boot sequence just transparently
use crypto swap if it is available.

Admittedly, this is sort of a question that needs a debian
developer's assistance.
