I'll see your CLI and raise you Files.. or how I accidentally made an Agent Operating System.

A couple of weeks ago I had a post over on LinkedIn about using FUSE to isolate my Pecan VMs such that they didn’t even need to have external read-write mounts to the filesystem. Everything could be done through an overlayfs-style implementation that allowed the Pecan Server to pull changes back into the host filesystem. The original implementation had tried to do this host-side by implementing a virtual filesystem using FUSE and then mounting that in the Pecan container. Unfortunately on macOS at least this didn’t do what I wanted since I had used FUSE-T to avoid MacFUSE’s increasingly annoying kernel extension dance. It turns out you can’t mount an NFS filesystem in Apple’s Containerization framework.
