This includes setting the Debian base image to a specific release rather
than the generic `stable` version, which can cause issues when assuming
package versions or external repository status.
This commit represents a large amount of work toward moving services to
a more standard approach to storing data, and a simplification in how
networks are managed.
This contains the culmination of work done privately for a few months,
and is intended to be a solid basis for other peoples' experimentations
with setting up single-node, home-server setups using Fedora CoreOS.
