Hope this isn't too irrelevant, but why would you want to do full disk
encryption? You're slowing down your machine by forcing it to do extra
processing and you're encrypting many many files that are publicly
available and don't have any personal information in them. I don't
really see the point of encrypting /usr/bin, /usr/sbin, /usr/lib, /lib,

Why not just encrypt the stuff that's specific to you?

Thanks, Tom
