Subject: [PATCH] service: don't warn if the pidfile still exists after
|
||
|
|
SIGCHLD
|
||
|
|
|
||
|
|
A service that drops its privileges may not be able to remove it when it
|
||
|
|
exits. The stale pidfile is not a problem as long as the service
|
||
|
|
carefully recognizes it on its next start.
|
||
|
|
|
||
|
|
systemd would produce a warning after the service exits:
|
||
|
|
PID ... read from file ... does not exist. Your service or init
|
||
|
|
script might be broken.
|
||
|
|
|
||
|
|
Silence the warning in this case. Still warn if this error is detected
|
||
|
|
when loading the pidfile after service start.
