Is it possible to install Ubuntu 11.04 with full disk encryption?

Previously versions have had an alternate install cd with a text interface where you could enable encryption for your drives. This one is fully graphical and is missing that encryption option.

NOTE: the alternate CD is no longer available since Ubuntu 12.10. From this last release version you can encrypt the entire disk from the normals Live editions (LiveUSB, LiveCD, LiveDVD). –  Lucio Feb 27 '13 at 23:18

What encryption mechanism (i.e. dm-crypt) does this use? –  Felix Mar 21 '12 at 11:33

It uses dm-crypt for encryption, complying with the LUKS specification, I believe. –  Flimm Mar 26 '12 at 11:38
