I’ve been running fedora coreos on my home servers for awhile. I really liked
the stability I got from bazzite, and have since enjoyed the stability of
fedora coreos. Since it’s an immutable system I’ve never quite known if I need
to reboot or not, and was unsure how to check for updates. Today I learned you
can use rpm-ostree status to see if your
fedora coreos system is up to date.
rpm-ostree status
For me it listed security advisories with a count of each severity unknown, low, moderate, and important.
