Subject: [PATCH] bus: when terminating our bus-actviated services that
|
|
exit-on-idle send STOPPING=1 via sd_notify()
|
|
|
|
This should fix a race where a service thatis idle drops its name, and
|
|
is immediately requested by another client, which causes dbus-daemon to
|
|
ask systemd to activate it again, but since systemd still assumes it is
|
|
running it won't do anything.
