Yes, and that is one of the tools that would be evaluated. My immediate problem is that it requires a working OS to rollback to the last filesystem snapshot if the configuration change (which is still not atomic) is interrupted.
The area where filesystem-level snapshots would be amazing is the /home partition, whenever a teacher asks the computer to be cleaned before an exam.
maybe the snapshot could be rolled back by a PXE bootable system. but for the second part, btrfs can do snapshots per subvolume, so if you could create a subvolume on user creation that could work
Btrfs and snapshots could help with atomicity, did you consider that?
