I believe Guix does a good job of managing system generations and only
snapshot user data. (My root is also on a faster ext4 file system, not
Btrfs.) Here is what I do. [1]
In order to avoid confusion with the live file system, I mount
snapshots volumes separately under /history. [2] My user data is
generally also encrypted and mounted to /home from networked folders
under /acct.
Hope that information is helpful to you.
Kind regards
Felix
