Oh cool. Yeah. The update pre/post snapshots are enabled by default so you need a bigger partition. I think they recommend 60g? But in the worst case you can turn them off.

Regatding bleeding edge thing. I think it is pretty stable for general use. SLES (opensuse enterprise) is using it as default for root fs enterprise deployments. I don’t think they would risk finantial loses using unstable filesystem.

I can imagine the problems will probably appear on large scale deploymets, maybe with deduplication. For example I am using btrfs on my home server in raid10 array… for abou 6-8years now. I had issue only once so far which was due to me being a dumbass.
