Comment 27 for bug 85640

For me cryptsetup with luks worked this way:

 * booting LiveCD feisty beta
 * installing cryptsetup in the lifesystem
 * partitioning the system in 4 partitions
 * formating and opening of luks encrypted devices for root home and swap (swap is onetimeencrypted)
 * starting graphical installer and installing the filesystems to the matching mapperdevices. boot unencrypted
 * chrooting in the rootfilesystem
 * mounting of /proc and /boot
 * updating the system
 * installation of cryptsetup
 * configuring of crypttab and the modules to be included in the initramfs
 * rebooting

It would be nice to have cryptofilesystem support in the ubuntu default installer. I think that it shouldn't be that much work anymore. debian supports cryptofilesystems in stable release, since etch was released.
