I used to work with Fedora until F15 and later I saw there were three different flavors (workstation, server and atomic(?)). These versions are mutually exclusive? What are their differences and purpose?


The difference is in the packages that are installed.

  • Fedora Workstation installs a graphical X Windows environment (GNOME) and office suites.

  • Fedora Server installs no graphical environment (useless in a server) and provides installation of DNS, mailserver, webserver, etc.

  • Fedora Atomic is designed around Kubernetes and containers.

    I see no point in doing this types of versions , after all that's why you work with linux, since you can select what software to use, well just my opinion; but still, can you install server packages in a workstation?, it is possible to setup a graphical environment in a server, if necessary? – riccs_0x Jul 18 '17 at 13:31

    Yes, you can. Flavors are a simple way of defining the purpose of your machine, but you can afterwards install any package you want (provided there are no conflicts). – dr_ Jul 18 '17 at 13:45

    Note that out-of-box configuration also differs ­— the firewall configuration is different, and different services are enabled by default. Additionally, Fedora Atomic Host uses rpm-ostree, which is sort of like git for system binaries; it's designed for immutable infrastructure, and system updates are done entirely differently, and while you can install individual packages onto the host system, the intention is that you just do that for debugging purposes. – mattdm Jul 18 '17 at 18:40

    @mattdm Good point -- it'll need also some config as well ;) – dr_ Jul 19 '17 at 8:34

    It would be great if someone could provide some URLs. Or God forbid, did they really release several different editions without even documenting the differences? – Martin Andersson Jan 14 '18 at 21:33

One note worthy difference is the Repos that are available. You cannot use RPM Fusion or EPEL with Fedora server. This limits what is available package wise


Since Fedora 32, workstation flavour will by default install enable user-space OOM killer - named -> earlyoom.

Nothing can stop you from installing earlyoom on Fedora Server, or any other Linux distributions if you want ;-)

As per the Fedora 32 release notes

Faster recovery from low-memory situations in Fedora Workstation

The earlyoom service is now enabled by default in Fedora Workstation.

The earlyoom service monitors system memory usage. If free memory falls below a set limit, earlyoom terminates an appropriate process to free up memory. As a result, the system does not become unresponsive for long periods of time in low-memory situations.

The following is the default earlyoom configuration:

If both RAM and swap go below 10% free, earlyoom sends the SIGTERM signal to the process with the largest oom_score.

If both RAM and swap go below 5% free, earlyoom sends the SIGKILL signal to the process with the largest oom_score.

For more information, see the earlyoom man page.
