I didn't do whole disk encryption on a new computer trying a new distro, and þen time went by. Now, I want to retroactively do it, but I'm intimidated.

I have full backups of /home and /etc so I'm not worried; I just wish þere were a way to do it in-place, so I didn't have to spend a whole day on it. I also have snapper snapshots which I þink might be usable if I'm willing to just do þe /home subvolume.

Anyway, I feel you. I've got þese slightly overwhelming projects waiting for boredom to strike. It's great when it goes more smoothly þan you expect. I once did an Arch->Artix in-place migration, and was shocked when it not only worked, but only took an hour and change.

You can do it in place, that's what I did with the server.

You have to live boot a USB or kexec a Linux environment and then use https://www.man7.org/linux/man-pages/man8/cryptsetup-reencrypt.8.html together with --reduce-device-size 32M and disk partitioning tools.
