One thing to add to this: Encryption keys are stored in memory (or else it doesn't work) This can also be leaked to disk (SWAP, for instance). I tend to either encrypt it all (apart from the boot partition) or don't bother at all. For me, it depends in how and where the system is used. Laptops travel with me and if they can be physically compromised, they get reinstalled with a fully new encryption key. Normally, the laptop is fully switched off when nog in use and the boot process, on the encrypted section, will check the boot partition with a known clean state. If it fails that check, there is a big warning and several services will fail to start. -- Joost -- Sent from my Android device with K-9 Mail. Please excuse my brevity.
