We routinely use the system message notification (available via the XMLUI control panel) to post warnings about upcoming system maintenance. Unfortunately, these warnings do not persist across Tomcat restarts. And, sometimes we'd like to script service restarts... a nice thing to do would be to give a warning with a countdown prior to a scripted restart. If only there were a way to script this. Likely the storage of the system notification will need to change (currently it resides in the somewhat ephemeral JVM), it could be moved to the much more sturdy site-wide metadata.
