Does sendmail uses an initscript or a systemd .service file ?

There's certainly an initscript. I'm not sure where to look for ".service" files. Directory "/lib/systemd/system" contains: -rw-r--r-- 1 root root 510 Oct 29 14:59 sendmail-client.path -rw-r--r-- 1 root root 849 Oct 29 14:59 sendmail-client.service -rw-r--r-- 1 root root 1402 Oct 29 14:59 sendmail.service I would guess that means it is using a ".service" file. There are symlinks to these from files in "/etc/systemd/system/multi-user.target.wants". I guess I will eventually get the hang of how systemd does things. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Don't know how old this guidelines are. As I'm was busy with SLES11-SP2 it could be that I've missed this. Nevertheless it should work after using systemctl by the system admin. Beside this missing rpm spec macros and as I'm using systemctl in the direct way I'd like to know why systemd is reporting this error about a missing /var/run/sendmail.pid? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Appreciated. I installed your package on my test system. I then rebooted. The bogus message is still there. I guess that doesn't solve the problem. The comment in the redhat bugzilla is as bit cryptic, but on my reading it does not seem to apply. That seemed to be, at least in part, about service shutdown. Sendmail does not drop privileges. The daemon, which creates the pidfile, sits there with full privileges. On an incoming connection, it may drop privileges in the child process after fork(), but that would not affect the pidfile. The sendmail client daemon runs with lower privileges, but its pidfile is where it does have sufficient privileges to create or remove that file. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

the pid file /var/run/sendmail.pid belongs to 17395 here:

sudo cat /var/run/sendmail.pid 17395 /usr/sbin/sendmail -L sendmail -Am -bd -q30m -om

we have either a race or systemd can not handle a simply pid file if more that one process us running (and both looks more like a bug of systemd). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This must be implemented in race-free fashion so that the PID file is only updated when at the same time it is verified that the PID previously stored in the PID file no longer exists or belongs to a foreign process. Commonly some kind of file locking is employed to implement this logic. .. IMHO it is race free as sendmail creates its pids only if all is OK (configuration, network, ..) and running. It is upto systemd to handle this, e.g. by a timeout or similar or will systemd upstream really will cause sendmail and other daemons to be rewritten due the new systemd isn't able to handle timeouts in a clear way? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The interaction between sendmail and systemd is racy. Having been part of the sendmail volunteer team, I think the RH people are correct that a patch would not be accepted for this. The whole point of such a patch would be to make systemd reporting more reliable at the cost of reducing the reliability of sendmail itself. At present, the pidfile is written by the running daemon when it is up and ready. The proposed patch would require that the pidfile be written by its parent process, based only on the hope that it will work out. As for what to do at opensuse? It's not my call, but I would not have any problem with setting it as WONTFIX. It's only a cosmetic problem anyway. And there are plenty of other log messages that we learn to ignore. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
