summary: D-Bus session services support activation via systemd user session
details: |
Verify that snaps that consume the D-Bus session bus can be activated by the
systemd-provided D-Bus session. This is tested by starting a systemd user
session, installing a snap that provides an activatable D-Bus service, and
verifying that the service is activated when a method call is made.
