@daandemeyer Wow that looks dead useful. Would that allow to run other container system like podman / docker in there long term?
I'm asking because I wanted to run ci/cd for a git I'm hosting, but everything being hosted inside nspawn containers, well. Yikes, I guess. And I absolutely refuse to polute the host with a mess as horrible as docker. No way no how.

@xogium Currently podman / docker don't nest within nspawn for the same reason that nspawn doesn't nest within nspawn (kernel mount shenanigans). Once we fix that you'll be able to run nspawn, docker and podman nested in nspawn (I think, there may be more issues with getting podman/docker running). If you want to run unprivileged podman/docker within nspawn they'll need to integrate with nsresourced and mountfsd (instead of using newuidmap/newgidmap like they do right now).
