So I have a strange question for the #Linux crowd — or more specifically, for the #RaspberryPi crowd. And possibly specifically #RaspberryPiOS (I'm not unwilling to consider others, but it is the most tested and has the tools for managing the RPi stuff.)
I would like to setup a configuration where the /home partition is encrypted with LUKS. I really would rather only /home for several reasons, including performance. Setting up the encryption is no real issue, but getting it to actually mount it on startup and prompt for the password (no I don't want a keyfile) is a problem. The normal initramfs stuff so easily setup on a desktop system seems to be really hard to get into a RPi distro and guides are way outdated. I can mount after boot, but not during.
This is a RPi4 (not 5.)
