great, let's see what others think. unfortunately i'll be very busy in
summer, and won't have much time to participate in this discussion. i'll
however try to follow it, and comment when i find time.

as both cryptdisks init script run in the boot/halt process, users
already see the warnings:

boot process:

cryptdisks-early start -> silent
cryptdisks start       -> prints warnings

shutdown process:

cryptdisks stop        -> silent
cryptdisks-early stop  -> prints warnings

that would be great. i tested it on my system, and it seems to work.
will test it on some kvm setups before uploading, but more testers are
always welcome, so your report would be much appreciated, before I
upload the new package (which I inted to do within the next three days).

greetings,
 jonas
