Introduce a counter that tracks how many configuration reloads have been successfully completed by the manager. The increment lives in manager_reload() right after the "point of no return", so failed reload attempts that bail out earlier (e.g. during serialization) do not bump the counter. It is accessible as a new ReloadCount property to org.freedesktop.systemd1.Manager (D-Bus) and ReloadCount to io.systemd.Manager.Describe (Varlink). Also add an integration test for ReloadCount that verifies that the new ReloadCount property increments by one per daemon-reload, accumulates correctly across multiple reloads, and that D-Bus and Varlink return identical values. Also tests that the counter reset after a reexec. Co-developed-by: Claude Opus 4.7 <noreply@anthropic.com> Signed-off-by: Simon Lucido <simonlucido@meta.com>
