We are occasionally being asked by Jenkins Enterprise customers how to make sure Jenkins is not performing builds after a restart, perhaps because it is being restarted due to maintenance or some major system reconfiguration.
Previously this was tricky, requiring a custom Groovy script (which we would do for you upon opening a support ticket). We just released a new "CloudBees Quiet Start" plugin which automates this simple task and provides an easy-to-use UI to control it.
Since this is a first release, please give us your feedback on whether you like this plugin or not and how you think we should be improving it. For example, do you want more options in the UI? Which ones?
