Related, I've always wanted to see someone other than Meta run EdenFS, to hear more reports of what it's like. Feels like there's massive overlap. [Edit: I've chatted with Astra Pro some on this too now, https://chatgpt.com/share/6ace7be6-68f8-83ea-ad68-0f9d144483... ]. https://github.com/facebook/sapling/blob/main/eden/fs/docs/O...

It's designed for container running, but ArtifactFS has some similarity in principle to me. The on-demand materialization. Quote: ArtifactFS is a Git-backed filesystem daemon (FUSE driver) in Go that mounts repositories as normal working trees while avoiding eager blob downloads. https://github.com/cloudflare/artifact-fs

I threw together my own jujutsu powered FUSE subtree project just the other night. This was basically one-shotted, just to see how it does it, to learn more, not really intended for use. But obvious overlap. https://github.com/rektide/jj-workfuse
