As the title says, is it possible to run LXC containers inside Fly VMs?
It should be. We just deliver a Linux VM with whatever distribution your (outer) OCI container sets up. You can, for instance, run Docker instead of a Fly.io VM. I don’t think there’s anything LXC wants that isn’t already in our VM kernel.
Appears to require a privileged docker container for that. What do I do now?
Also, LXD/LXC has to be installed via snap. But sanps are not supported on fly.io
