Ok, so I've taken a stab at debugging this thing and got it to work; see
the attached patches; some of them also contain changes which I needed
to be able to run the script with set -eu. I think it would make sense
to apply these, too, so I'm attaching them as well. I'm not squashing
together the patches 1 and 5, and patches 6 and 8, since I think it may
show the difficulties more clear.

You can get the same patches also from the git repository at:

http://christianjaeger.ch/dyn/pubgit/gitweb?p=cryptroot-debugging.git;a=summary

This git repository also contains my whole debugging history in the
"debugging" branch, in case you're interested in more details. (It also
contains a patch for usage under set -eu to the hook-functions file from
the initramfs-tools.)

Christian.
