So I have VM with Jenkins in production and I've cloned it to try some configuration.
When I go to Job Configuration on clone, check "Restrict where this project can be run", and fill in label, I'm getting following: "Slaves in label: 2". It's OK, but hyperlink in word "label" still contains fqdn of production VM. Since all other links were transformed by Jenkins from fqdn of production to IP of clone, this was unexpected.
And this could result in failure in production because moving from clone to prod. was too easy and might be noticed only by looking into address bar. Honestly, I don't do it that often.
Example:
I've had "jenkins.example.org" and clone has "192.168.0.15".
So I will have page with address "http://192.168.0.15/job/test/configure", with "Slaves in label" refers to "http://jenkins.example.org/label/label-test" instead of "http://192.168.0.15/label/label-test"
