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
