{microshift-short} is designed to make control plane restarts economical and be lifecycle-managed as a single unit by the operating system. Updates, roll-backs, and configuration changes consist of simply staging another version in parallel and then - without relying on a network - flipping to and from that version and restarting.

=== Installation

Previously, the greenboot health check marked some healthy Image mode for {op-system-base} systems as unhealthy due to a 300-second timeout, which was insufficient for systems with slow networks. Beginning in {product-title} 4.18, the default greenboot wait timeout has been extended to 600 seconds to provide more time to download images and ensure accurate system checks.
