(My root is also on a faster ext4 file system, not > Btrfs.) Here is what I do. [1] I agree, unless you very high requirements to minimize downtime in case of failures, thus justifying the need of snapshotting the root fs and backing it up to external storage, just snapshotting /home should be good enough for most users. I'd still opt for a flat subvolume layout to preserve the ability to snapshot / at all in the future, in case you ever need to.

Do note that you may run out of inodes if your store grows very large. zstd compression also helps a lot ot keep /gnu/store growth in check, and should reduce wear to flash based storage. -- Thanks, Maxim
