From 53964fd26b4a01191609ffc064aa8ccccd28e377 Mon Sep 17 00:00:00 2001 From: Mike Yuan Date: Tue, 9 May 2023 00:07:45 +0800 Subject: [PATCH] core: refuse dbus activation if dbus is not running dbus-broker issues StartUnit directly for activation requests, so let's add a check on bus state in bus_unit_queue_job to refuse that if dbus is not running.
