Original commit message by Thomas Koehler:
Newer device mappers create /dev/mapper/grml-crypt_DEV
as a symlink to /dev/dm-X, no longer as a block device.
Unfortunately, after mounting, you only see /dev/dm-X in
/etc/mtab and /proc/mounts, which broke the "stop" command
in grml-crypt. By looping over all /dev/mapper/grml-crypt*
files and checking if this is the correct one, this problem
can be fixed.
Thanks: Thomas Koehler <jean-luc@picard.franken.de>
