I recently started using Fedora with btrfs, which I think was the default on install. So far all I’ve noticed is that backups and restores are really fast and easy.
Are there any important things to be aware of, like speed, drive lifespan or energy efficiency?
This is how I understand subvolumes, that unless specified otherwise, they’re excluded from snapshots taken of parent folders, so by making /home a subvolume is less about taking snapshots of that folder, and more about ensuring that taking snapshots of / doesn’t include /home.
