GEFS is ready for wider use in the Plan 9 world. I still make no guarantees on your data safety.

Editing to add -- since not everyone on the fediverse has context: GEFS is a new file system I've been writing. It aims to be crash-safe, reasonably performant, with the features you'd expect, including snapshots, checksumming, and so on.

For more info -- I have a paper on how it works up: https://orib.dev/gefs.pdf
