Bug description:
  Binary package hint: cryptmount

  9.10 installed with encrypted "home".
  Had root on /dev/sda1, swap on /dev/sda2, and manually created "data" partition on "/dev/sda3"
  When I deleted /dev/sda2 partition (wanted to move swap to the second HDD) - ubuntu killed my "data" partition!
  I suppose the problem is that /dev/sda3 became /dev/sda2 and the cryptswap utility just killed all the data (about 80 gigs!), because /dev/sda2 is in the /etc/crypttab file as a swap partition...
  Cryptswap should check the type of partition before mounting it as swap.
