I have default installation of Jenkins for RedHat related OS.

Excerpt from the /etc/systemd/system/jenkins.service file:

Environment="JENKINS_WEBROOT=%C/jenkins/war

After systemctl start jenkins ps command shows me:

jenkins   7128  0.2  9.7 16923192 3180692 ?    Ssl  Apr19   2:53 /usr/bin/java -Djava.awt.headless=true -jar /usr/share/java/jenkins.war --webroot=%C/jenkins/war --httpPort=8080 

And the content ~jenkins directory:

# ls -l ~jenkins
total 32
drwxr-xr-x.  3 jenkins jenkins   21 Apr 19 13:12 %C 
...

Is this a typo or should %C be converted to something?

Of course, I will change it, because I have to adjust my Jenkins installation.

OS: CentOS Linux release 7.9.2009 (Core)
