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.
|
||
|
|
|
||
|
|
Replaces #27570
|
||
|
|
Closes #26799
