Can one run a host system program under the same cgroup as a container?
Coud this be achieved with something like the following?
cgexec -g *:lxc.payload.container command -argument
It’s technically possible, yes. Not usually advisable as the container may restart causing some issues. Also your program using container resources may lead to confusing output in the likes of top/htop inside the container as your process won’t be visible in there.

Thanks!
It’s only so that host side backup things run on the same resources as the container.
But the container sees there are resources used (stolen, st in top)?
Which is the right one lxc.monitor.container or the payload one?
Yeah, exactly, the container will see the memory/cpu usage but without being able to see the process consuming the resources.
It’s the payload cgroup you want to use for this.

Just out of interest and lack of knowlegde: Why is there only one PID in init.scope/cgroup.procs? Where are all the other processes?
They’re most likely under system.slice/WHATEVER.service/cgroup.procs
