Package: systemd Version: 237-1 Severity: important Tags: upstream Hi!
The upstream commit db256aab13d8a89d583ecd2bacf0aca87c66effc "core: be stricter when handling PID files and MAINPID sd_notify() messages" breaks several daemons in Debian. Known issues exist for - munin-node https://bugs.debian.org/889073 - ulogd2 - dnsmasq https://lists.debian.org/debian-user/2018/01/msg01331.html and possibly others. Symptom is a timeout during service start, constant service restarts (if configured) and log messages like: Feb 2 14:22:49 HOST systemd[1]: ulogd2.service: Permission denied while opening PID file or unsafe symlink chain: /run/ulog/ulogd.pid Feb 2 14:23:54 HOST systemd[1]: munin-node.service: Permission denied while opening PID file or unsafe symlink chain: /run/munin/munin-node.pid Problem lies, as far as I understand the change, in the permissions of the directory in which the PIDfile is created by the daemon. In all cases it does not belong root:root but the respective service user: HOST:/run# ls -ld ulog munin drwxr-xr-x 2 munin root 100 Feb 2 14:50 munin drwxr-xr-x 2 ulog ulog 40 Feb 2 14:24 ulog My quick'n'dirty workaround for munin was to change the PIDfile path to just "/run" in both the systemd unit and the configuration file and for ulogd2 I converted the unit from Type=forking to Type=simple, omitting the PIDfile completely. But this can only be a workaround in my opinion, because the upstream change changes an assumption on how and where PIDfiles can work without any prior notice. This needs to be changed to a non-fatal warning and not an error, IMHO.
