Similar to my thread about the @server-hardware-support group, the
@container-management group also takes up a good chunk of space (38MB
above the minimal install) in the default Server install, as well as
including an additional available-by-default service.

longer critical from that perspective.
This leaves Cockpit: one of Cockpit's more popular features is the
ability to manage Docker images and containers from the UI.
