Ok, udev creates the /dev/dm-* devices and also removes them. At the 
time the cryptdisks scripts are executed at shutdown, udev is not 
running (as FJP said).

The proper "fix" for this seems to be a post-Etch thing (involving 
changes in the kernel, udev and libdevmapper), and the issue seems 
mostly cosmetical, so I'll mark the bug as such.
