Fedora Magazine reports
that the Fedora CoreOS distribution is now deemed ready for use.
“Fedora CoreOS is a new Fedora Edition built specifically for running
containerized workloads securely and at scale. It’s the successor to both
Fedora Atomic Host and CoreOS Container Linux and is part of our effort to
explore new ways of assembling and updating an OS. Fedora CoreOS combines
the provisioning tools and automatic update model of Container Linux with
the packaging technology, OCI support, and SELinux security of Atomic
Host.“
