** Description changed: [Impact] Systemd Unit file doesn't read any settings by default [Description] The unit file shipped with the Xenial pacemaker package tries to read environment settings from /etc/sysconfig/ instead of /etc/default/. The result is that settings defined in /etc/default/pacemaker are not effective. Since the /etc/default/pacemaker file is created with default values when the pacemaker package is installed, we should source that in the systemd unit file. [Test Case] 1) Deploy a Xenial container: - $ lxc launch ubuntu:xenial pacemaker + $ lxc launch ubuntu:xenial pacemaker 2) Update container and install pacemaker: - root@pacemaker:~# apt update && apt install pacemaker -y - 3) Check the systemd unit file for the "EnvironmentFile" option: - root@pacemaker:~# systemctl cat pacemaker | grep EnvironmentFile - EnvironmentFile=-/etc/sysconfig/pacemaker - EnvironmentFile=-/etc/sysconfig/sbd + root@pacemaker:~# apt update && apt install pacemaker -y + 3) Change default pacemaker log location: + root@pacemaker:~# echo "PCMK_logfile=/tmp/pacemaker.log" >> /etc/default/pacemaker + 4) Restart pacemaker service and verify that log file exists: + root@pacemaker:~# systemctl restart pacemaker.service + root@pacemaker:~# ls -l /tmp/pacemaker.log + ls: cannot access '/tmp/pacemaker.log': No such file or directory + + After fixing the systemd unit, changes to /etc/default/pacemaker get picked up correctly: + root@pacemaker:~# ls -l /tmp/pacemaker.log + -rw-rw---- 1 hacluster haclient 27335 Mar 7 20:46 /tmp/pacemaker.log + [Regression Potential] The regression potential for this should be very low, since the configuration file is already being created by default and other systemd unit files are using the /etc/default config. In case the file doesn't exist or the user removed it, the "-" prefix will gracefully ignore the missing file according to the systemd.exec manual [0]. Nonetheless, the new package will be tested with autopkgtests and the fix will be validated in a reproduction environment. [0] https://www.freedesktop.org/software/systemd/man/systemd.exec.html
