Never used systemd-homed, but i know an alternative to full disk encryption is having the root partition unencrypted, and the home partition unlocked at boot. For a single user machine at least, i don’t see any difference when using it than unlocking at login. But then having 2 partitions is mandatory, and that may be a problem when running out of space.
Yeah, but there is almost never a need for keeping an older version of linux, unlike for Windows 10 since win11 has ridiculous system requirements
