Bug or stupid: disable checked, but DynDNS updated…

[rcfa]

I'm preparing a little box for potential deployment, so I want to get as many settings done without pulling the trigger, because right now another system is still doing the job.

So I prepared what will be the future DynDNS rules, but I checked the "Disable" checkmark, assuming that with that checked no DynDNS updates will happen.

However, after saving my settings, the IP addresses appear green, and going to the host, results in me ending on my new, instead of on the old system.

So is this just a side effect of saving the settings, but otherwise DynDNS is disabled for that particular entry, or is the disable checkbox ignored (bug), or does it disable something entirely different than I think it should disable?

In any case, this could have turned into a minor disaster if I hadn't caught it…
