I work at a company that takes security very seriously (like most). Our IT guy came in today to prepare us mentally to re-install our systems after he'll apply the new encryption policy (which will basically scrape our HD clean).
For our team this means about a week of re-configuring, installing, and tweaking our desktops until we are back to work capacity - anyone who has to re-install a development machine probably knows what I'm talking about. So, I guess my question is if there's any way to perform full disk encryption on a linux (ubuntu >= 9.04) system without having to re-install EVERYTHING [sigh]. IT guy said there isn't any - please prove him wrong. thanks :)
