So, I'm going to do a bunch of reformatting etc on my laptop over the next 2 or 3 days to get it wiped and fde'd before I go to defcon, and getting it provisioned with all the ctf tooling I need. Any recs beyond just LUKS on the root partition? Should I do LUKS over swap too?
The right approach is to use ephemeral encryption for swap (assuming you don't care about hibernation). There should be a way to set up a dm-crypt mapping with a random key and automatically mkswap it on boot, on your distro (Gentoo has this). No need for LUKS.

IIRC I have the same setup on my Arch box, I can double check the config if you use that.

Yeah I would be using arch. Tbh I'm not worried that much about swap since I don't plan to have my laptop powered on between locations since sleep mode is wonky, though, so I might just, like, skip it?
