Maintaining Onyx is easy, because there won't be much for you to do.

Onyx is a stable, long-term solution intended to be dropped in place and pretty much forgotten. Of course there will be the occasional security update or the inevitable hardware failure, and thats why Blacksail Software, LLC is working hard to create a dashboard-like application for monitoring and maintaining several Onyx systems simultaneously. This application will allow you to monitor the health of all your systems at a glance, manage packages, services, and scheduled tasks en masse, and deploy security updates to all of your systems at once. Think of it as a one-to-many multicaster for all of your systems running Onyx, allowing you to configure all of your systems across the board with one motion.
