The Jenkins 2.332.2 upgrade guide notes that Jenkins has switched from System V init to systemd. Read more about it at https://www.jenkins.io/doc/upgrade-guide/2.332/ The Jenkins 2.332.2 changelog notes that Jenkins has switched from System V init to systemd. Read more about it at https://www.jenkins.io/changelog-stable/#v2.332.1 The "What's new in Jenkins 2.332.2 livestream" notes that Jenkins has switched from System V init to systemd. Learn more about it at https://youtu.be/JO0BSpVjUJ8 The "Managing systemd services" page in the Jenkins documentation gives more information about managing systemd services with Jenkins. See https://www.jenkins.io/doc/book/system-administration/systemd-services/ The "Managing the systemd service on CentOS 7.9" video by Darin Pope provides more information at https://youtu.be/MkokjTQ2ngc?list=PLvBBnHmZuNQJeznYL2F-MpZYBUeLIXYEe > What's more, I also noticed that a "%C" directory has been created in > Jenkins' home which only contains a jenkins/war subdir and the contents I > list below. > > In the systemd service definition > (/usr/lib/systemd/system/jenkins.service) indeed I now see: > > -------------------- > # Location of the exploded WAR > Environment="JENKINS_WEBROOT=%C/jenkins/war" > > # Location of the Jenkins log.

Per https://www.freedesktop.org/software/systemd/man/systemd.unit.html#Specifiers , the '%C' should be expanded by systemd to be the system cache directory. On my Red Hat Enterprise Linux 8 that is /var/cache. Based on https://issues.jenkins.io/browse/JENKINS-68313, it appears that the CentOS 7 implementation of systemd does not support the '%C' specifier. Replace it with the text for the cache directory on your operating system. Mark Waite -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
