[Pkg-cryptsetup-devel] Bug#373973: rewrite cryptdisks as a wrapper around cryptsetup

[Jonas Meurer]

Package: cryptsetup
Version: 2:1.0.3-2
Severity: wishlist

cryptdisks should be a wrapper around cryptdisks, comparable to mount.
basicly it should do the same as the current cryptdisks initscript,
except that it can be invoked from the commandline.

cryptmount/cryptdisks should support dynamical devices which are not
configured in /etc/crypttab as well. the syntax could look like:

o setup plain crypt-disk named "cusb" (not defined in /etc/crypttab)
cryptmount /dev/sdf4 cusb
o setup luks crypt-disk named "cstick" (not defined in /etc/crypttab)
cryptmount /dev/sde1 cstick -o luks,key=/etc/keys/cstick,timeout=5

ideally the wrapper should be written in C, to make it faster than the
current bash shell script.
