Hierarchical #cgroup is really cool. You can run systemd within docker.
While the benefits are not obvious.
Consider. being able to test / integration test large ansible playbooks that depend on ansible.builtin.service.
For those interested:
docker run --privileged --security-opt seccomp=unconfined --cgroup-parent=docker.slice --cgroupns private ...
Be sure to remove getty.target.wants in your docker image or you will drop out of your graphical session on the host.

Atemu#TIL #cgroups' memory.current metric includes any #pagecache entries that a process in the #cgroup caused to be inserted, even if other processes are accessing it too.
This means that anything related to #systemd unit's memory accounting also inherits this property.
If your #emacs systemd unit reports insane memory usage (usually ~10G for me), this is why.
It's actually not emacs' fault for once ;)
