The only reason why I don't use Linux (even though I prefer Linux over Windows, and can do everything faster and more efficiently) is because each time I try to learn about dm-crypt I give up.

Can someone point me in the right direction for full OTFE on Linux (like TrueCrypt)?

Why not just use TrueCrypt? – ubiquibacon Jul 14 '11 at 1:02
TrueCrypt doesn't work on system partitions in linux – null Jul 14 '11 at 1:06
I'm not a TrueCrypt guru, but I'm pretty sure it does. – ubiquibacon Jul 14 '11 at 1:43
I am not a TrueCrypt guru, and with experience and visiting TrueCrypts website, that it does not work w/ linux system partitions. Please stop trying to argue my point; also I stated clearly that I want to use dm-crypt – null Jul 14 '11 at 1:50
So what does this mean: "Free open-source disk encryption software for Windows 7/Vista/XP, Mac OS X, and Linux" – soandos Jul 14 '11 at 1:54

LUKS can't encrypt the /boot partition, but everything else including your root partition can. That means GRUB and your kernel won't be encrypted, but everything else, including your files, programs, and logs, will.

This is similar to how TrueCrypt works. It has its own unencrypted bootloader that decrypts and runs Windows.

Many distributions allow you to encrypt entire partitions during installation. Fedora does using the normal installer, just check Encrypt this filesystem in the partitioning setup. Ubuntu also permits you to encrypt whole partitions, but you must use their alternate install media to do so. Live media only supports home directory encryption.
