When adding log recorders with CasC:

jenkins:
  log:
    recorders:
    - loggers:
      - level: "ALL"
        name: "org.csanchez.jenkins.plugins.kubernetes"
      name: "kubernetes"

The logger is properly loaded and configured. But the file $JENKINS_HOME/logs/custom/kubernetes.log is not created..

Upon Controller restart, then it works..

Evidence

The configuration as code initialization kicks off after the CustomLogs component initialization:

INFO	jenkins.model.Jenkins$5#runTask: Took 36194ms for CustomLogs.startCustomHandler by pool-6-thread-18
[...]
INFO	jenkins.model.Jenkins$5#runTask: Took 63003ms for ConfigurationAsCode.init by pool-6-thread-

And CustomLogs initialization store a reference of the list of recorders that is obsolete

I think this is caused by:
