Hello.In context of a modern systemd-managed user session, is there a separate dbus activation environment, or is it merged with systemd? If one intends to manage environment variables, is systemctl (or org.freedesktop.systemd1.Manager Environment) enough?
A variable added by dbus-update-activation-environment (even without --systemd option) shows up in systemd activation environment. I couldn't find a pure dbus service to check if reverse is true.
