The ArtifactFS thing looks neat. I love this thing: https://github.com/cloudflare/artifact-fs/blob/main/examples... - it's kind of a generic image that turns into "another image" based on an argument you pass in. I recently built something similar for my own project that does the same thing except for Dockerfiles (needed for my stuff because cloud machines don't understand my registry!).

I wonder if I can fork/extend ArtifactFS for other types of content addressed storage. My registry is very git-like in some ways - it has an index, files are content addressed, etc.
