Public bug reported: 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.
