Not at all; 'break 2' has the effect that no other lines from /etc/crypttab
will be processed, which is definitely not what we want.

Bug description:
  On multiple fresh installs since beta release 2 i have been experiencing this issue:
  during boot up, i receive the message "could not mount /dev/mapper/cryptswap1 M for manual S for skip"
  obviously I'm expecting no message to show up at all and it should boot perfectly fine. I do however believe that i have found where the problem lies, it is in /etc/fstab
  This is how the original file looked:

  # /etc/fstab: static file system information.
  #
  # Use 'blkid' to print the universally unique identifier for a
  # device; this may be used with UUID= as a more robust way to name devices
  # that works even if disks are added and removed. See fstab(5).
  #
  # <file system> <mount point>   <type>  <options>       <dump>  <pass>
  proc            /proc           proc    nodev,noexec,nosuid 0       0
  # / was on /dev/sda7 during installation
  UUID=482c5b33-9ce8-4575-b787-cddeb1e93a5e /               ext4    errors=remount-ro 0       1
  # swap was on /dev/sda8 during installation
  #UUID=eb23dadc-8e08-4769-8fc5-0b1216b67e5b none            swap    sw              0       0
  /dev/mapper/cryptswap1 none swap sw 0 0

  
  i believe the problem is that the following line of:
  #UUID=eb23dadc-8e08-4769-8fc5-0b1216b67e5b none            swap    sw              0       0

  is not supposed to be commented out, i believe this happens somewhere
  in install. The ghetto fix for this is simply to remove the comment on
  it, but it definitely should not be happening...

  i have also found a eerily similar problem from Ubuntu 9.10 Bug
  #490760  which is a "duplicate" of another bug that is why i
  classified this as cryptsetup, because that bug was.
