That's a good point, I've completely forgot, when I've said in another
email, that I _could_ live with a cryptsetup package whose removal fails
if the are still open devices left.

Though this is another issue:
Wouldn't it make sense to try at the very end "just before
shutdown/reboot" to close any remaining _non managed_ dm-crypt devices?

Perhaps we should as Milan, if the same effect is automatically done by
the kernel itself.

Out of curiosity: Did someone from the policy guys came and request this
from you? Cause we had it that way for some time now.

Nice to hear :-)
