Kubernetes gives me a much more powerful multi-machine view, and if I'm debugging individual nodes, I probably don't want to merely *list* containers - I likely want to debug them, and that requires knowing the launching tool anyways: ``` # docker run -d -ti centos sleep 1h 531e395deda5a47f78f97089233fde45f214b1dd77597f452c6fa17ee9a5770e # # machinectl MACHINE CLASS SERVICE 531e395deda5a47f78f97089233fde45 container docker 1 machines listed. # machinectl login 531e395deda5a47f78f97089233fde45 Failed to get login PTY: There is no system bus in container 531e395deda5a47f78f97089233fde45. # ``` But `docker exec` works of course. > Currently machinectl will list all containers running via > systemd-nspawn, rkt, libvirt-lxc > and VMs running under libvirt.

I guess I've never had the problem that I've been simultaneously using nspawn, docker, and libvirt-lxc and been confused which container framework I was using =) > I think having this view is useful.

For example, I posted this a while ago: https://github.com/cgwalters/homegit/commit/dfe7069169e1043fe43a36af1af57378185dd888 Now ported to bubblewrap: https://github.com/cgwalters/homegit/blob/master/dotfiles/bashrc#L22 I just don't see the value in chatting with systemd every time I type `make`.

Anyways, I'm not arguing *against* the feature so much as I'm just venting about the insane number of daemons talking to each other just to launch a single `sleep` process =) But I'd still like to be sold more on `machinectl` for "non-init" containers.
