Title:
  Twofish LUKS Support in Alternate Installer

Status in “cryptsetup” package in Ubuntu:
  Expired

Bug description:
  In the Ubuntu Alternate installer, the option for using Twofish
  appears to have been removed around the Maverick or, possibly, Natty
  time frame.  The option to install using LUKS onto Twofish partitions
  was present in Lucid, but some time around Maverick or Natty it was
  removed and now this option is no longer available when using the
  alternate installer to install a LUKS partition.

  It would be preferable to have this option back, as Twofish is a very
  viable cipher which has very high strength, yet is reasonably fast.
  It is, of course, possible to create Twofish partitions post-install,
  but having this feature during the install itself is very useful,
  especially for the root partition.  Further, this feature existed in
  Ubuntu previously.
