Is there a way to do full disk encryption after the install?
I have Ubuntu 11.10 installed with /home encrypted but really need the whole drive encrypted. I would really like to do that with out a re-install. Is there anyway to do that?

LUKS in-place encryption exists. But you need to set up your environment a little as per the pictures:
(Also see this question)
No. Part of full disk encryption, Truecrypt or otherwise, is writing random data to the hard drive.
Best you could do (without a re-install) would be to migrate your home to encryption or make a encrypted data partition. You could use Truecrypt or LUKS (I personally use LUKS).
crypttab
, fstab
, make a separate /boot
partition, copy everything over to a new encrypted volume. It's hard, though. I would re-install everything copy data back as well.
