Seeing that user Flatpaks are installed in the home folder, I see this as an interesting strategy. EXT4 still beats BTRFS in certain read/write benchmarks. My only problem being that you lose provisioning.

I don’t see a lot of people talking about this here, but BTRFS subvolume provisioning is probably the best reason to use BTRFS - and BCacheFS - not just CoW or snapshotting.

The old way, of having a set beginning and end of a partition, is like caveman technology to me now. Subvolumes are here to stay and I am happy about that.

If I need to do a little distrohop now, even though I wouldn’t (rpm-ostree rebase go brrrr), all I’d do is delete an recreate the “@” subvolume (or the root subvolume) without touching another partition or subvolume. All storage space is shared between subvolumes, basically, removing that boundary distinction between them, so I get to keep the files, permissions and meta data in my “@home” and my “@var” subvolumes, even though I get rid of the old “@” to replace it with a new one.

Therefore the idea of having storage that is reliant upon partitioning, ordering sectors one after another, having to defragment and keep strict separations between them is absolutely archaic to me. I’ll gladly take a slight performance hit just for the convenience of avoiding all that.
