Encrypting the home folder

[amber bolt]

I'm desperately trying to encrypt my home folder, without risking an unbootable system or anything like that.

What systemd-homed does sounds pretty promising but also pretty scary. Luks will not work because I have no seperate home partition (and I'm not comfortable creating one, risking all my data in the process).

My system currently has three partitions: /boot (don't ask me why this exists alongside the next one), /boot/efi, and / (btrfs)

There must be an easier way to simply encrypting the home folder. Any idea?

Edit: Would this work? https://wiki.archlinux.org/title/ECryptfs#Encrypting_a_home_directory

so I just stumbled upon fscrpt (https://wiki.archlinux.org/title/Fscrypt), but its requirement for ext4 has me worried. Does that only apply to the encryption of entire partitions or is encryption of specific files generally only possible with support on the filesystem level? I'd expect it to work fine on btrfs, but I'm not very fond of accidentally formatting my home or something like that

it kinda also seems like It'd need a separate home partition as well. Can anyone clarify this for me?
