I'm trying to implement the Memory Erasure feature from Tails on my Ubuntu 11.10 machine. The documentation is here: https://tails.boum.org/contribute/design/memory_erasure/ This works on a Debian build (TAILS). My question is how can I implement this on Ubuntu? I can't get kexec to execute the new kernel (memory wipe kernel), it just shutsdown normally. Anyone here have experience with Kexec? The reason I would like this is for my companies laptops. They all use Ubuntu 11.10 (hardened) and LUKS encryption. I realize a cold boot attack is mostly impractical but I don't want to risk it when these laptops will be out in the field. Thanks for any help!
