Change jenkins root configuration config.xml location
I am setting up a customized Jenkins. My jenkins home is
echo $JENKINS_HOME
/srv/jenkins
This means that the location of my config.xml file is
$JENKINS_HOME/config.xml
/srv/jenkins/config.xml
But I want Jenkins to read the config.xml file from under
$$JENKINS_HOME/config/config.xml
/srv/jenkins/config/config.xml
You might ask why ? Because since this is a customized Jenkins, Im am deploying the config.xml file on runtime in a Helm chart on Kubernetes and this file will change based on the customization by different teams. And I want this file to persist after Ive done the modification during the InitContainer phase of my pod startup.
One thing I tried was to create a softlink
jenkins@25bea2ece6a9:~$ cd /srv/jenkins/
jenkins@25bea2ece6a9:~$ ls -ltrh | grep config.xml
lrwxrwxrwx 1 jenkins root 30 Nov 23 16:01 config.xml -> /srv/jenkins/config/config.xml
When I startup the Pod, this link is present but within 10 seconds, Jenkins overwrites this link with an actual file and all my configurations are overwirtten.
So can I tell jenkins to read the config.xml file from somewhere else ?

You can use the configuration as code plugin to inject your configuration at run time instead

No, config.xml is hardcoded in source and until you want to recompile Jenkins by yourself this cannot be done. config.xml is written and by jenkins when loaded.
Great people working on Configuration as Code plugin want to bring this philosophy to jenkins but until it's stable (and it's not currently) you have to use init.groovy scripts for automation.
Jenkins currently provides access to it's initialization through groovy hooks (https://wiki.jenkins.io/display/JENKINS/Groovy+Hook+Script)
And what you can do is write init.groovy script which can issue reload on copied config.
You can do that using initialization state:
import hudson.init.InitMilestone
if(Jenkins.instance.getInitLevel() == InitMilestone.COMPLETED){
// copy config.xml
Jenkins.instance.reload()
} else {
// sleep for a while, do some other stuff
}
