[Bug 1283614] [NEW] Warning on dpkg-reconfigure

[Sworddragon]

Public bug reported:

I'm using Ubuntu 14.04 dev with cryptsetup 2:1.6.1-1ubuntu1 and on a
"dpkg-reconfigure cryptsetup" I'm seeing the following warning:
"WARNING: you need to set all of cipher, hash and size for the plain dm-
crypt mapping cryptswap1 in /etc/crypttab."

This is the content of my /etc/crypttab: "cryptswap1 /dev/sda5
/dev/urandom swap,cipher=aes-cbc-essiv:sha256". But I'm not sure if the
related entries are missing because my installation is a bit old or if
they are also on new installations missing.

** Affects: cryptsetup (Ubuntu)
