Encryption on Ubuntu Lucid after installation

[danh000]

I'm a relative newby to Linux so forgive me if this is a simple question.

I know that if you install Ubyuntu using the alternate CD, you can create a whole disk encrypted installation, but what about after a normal installation? What is the best procedure to use to get more than just the home folder encryted?

Installation of Fedora 13 gives the option during a normal install to encrypt more than just the home folder.

You can fully encrypt a system afterwards... but it's tedious and a lot can go wrong. It's a lot simpler to start just over again with the installation of a fully encrypted system.

I really only want to encrypt my Ubuntu partition. I have a laptop with a multi-boot setup with Windows 7, Fedora 13 and Ubuntu 10.04 all residing in their own partition. Because of this setup I really can't use whole disk encryption. Sorry if I mis-stated what I want to do.

I do use Truecrypt on my Windows 7 partition and it works great but encryption of a Linux system partition is not supported.
