Comment 17 for bug 325690

In some earlier versions of the ubuntu installer, it was possible to encrypt the whole drive - whole means excl. /boot.

So I have a partition of sda1 and sda5, where sda1 is /boot and sda5 contains the LVM part with "system and swap"

2.6.27-11-generic is the latest kernel, where cryptsetup is still working,
config-2.6.28-8-generic does not offer to enter an ecryption key and thus fails.

The 2.6.27-11 fails on setting up the lvm part, so I have to do that in the initramfs (busybox?) shell with

- kvm
- kvm> lvchange -ay /dev/mapper/swap
- kvm> lvchange -ay /dev/mapper/system
- ^D (or exit)
- ^D
