I recently bought a new laptop with a 16Gb mSATA SSD cache drive. I haven't used that one yet.I have, however, opted for Ubuntu 13.04 with Full Disk Encryption for the main partition (is that what's called LUKS?).With bcache making it's way into 3.10, I'd like to take advantage of the aforementioned cache drive.According to this, one has to format one's backing and cache drives in order to take advantage of bcache.My questions are:Which order do I proceed in? Set up bcache, then (re)setup LUKS or the other way around?Except for the few files pertaining to the encrypted setup (incl. /etc/fstab), can I tar/rsync/whatever the rest of the existing fs to another disk, set up bcache and LUKS and then tar/rsync/whatever back and expect things to work?Are there other things I should know about?
