Does anyone know how to do a full disk encryption of Ubuntu 7.10?

Preferably it would store the key on an external USB drive.

Use TrueCrypt.  It is free (open-source), and works very well.  It will work precisely for what you want to do.

I should also say that if you intend to use something like this to encrypt even the boot disk itself, you will be unable to do it.  These applications require the operating system be up in order to use them.

If you do want that, then you're looking at something like SafeBoot, that can work with an Alladin eToken or the like.

I should have added that it needs to encrypt everything but /boot :)

Hi csullins ,

another option perhaps may be use of LUKS Encryption

This answers your question.  TrueCrypt can do that.  I thought about what you wanted before, but wasn't sure if it could be done.  This person claims to have done it.

One issue I could see is that it would be somewhat difficult, but not at all impossible, to make the "key" file work from a USB flash drive in this case.  The problem you'll find is that the operating system isn't yet fully up, and you're going to be relying on the drivers installed in the kernel to allow you to see a USB flash drive, as well as mount it as a file system to use it.  After all, it's still booting and doesn't yet have access to the root file system.
