- Yes, LXC can be built on Android and we actually build test it regularly
- Yes, you can run Android as a container on LXC or LXD without needing a VM. That’s what Anbox does.
- I don’t think anyone tried or managed to get LXD fully built using musl-libc, but there are no real technical blockers, likely just a bunch of patches needed for anything that musl doesn’t lik (kinda like what we had to do for liblxc).
