Subject: [PATCH] systemd-notify: Always pass a valid pid to sd_pid_notify
|
|
|
|
|
|
|
|
|
|
If the option --pid was used, take the pid from this option, unless take
|
|
|
|
|
the parend pid. Using 0 as pid (ucred of systemd-notify) will result 99% of the
|
|
|
|
|
time in a failure with this error: "Cannot find unit for notify message of PID"
|
|
|
|
|
|
|
|
|
|
Shouldn't we use always the ppid, since the MAINPID is something else ?
