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 ;)

When su - error "Failed to connect to bus no medium found"
Investigated causes based on https://njroute22.com/failed-to-connect-to-bus-no-medium-found
Image1: $ systemctl status dbus. "CGroup" led me to systemd control groups.
Image2: $ systemd-cgls. From entry user-1234.slice ONLY configurations for originally created host user (i.e., ID 1234 user in sudoers), BUT NO ENTRY for root (i.e., user-0)
Q: Can root be made a member of systemd control group like user-1234 is?
