These operating systems differ from Fedora Workstation as they replace the [DNF](https://docs.fedoraproject.org/en-US/quick-docs/dnf) package manager with a much more advanced alternative called [`rpm-ostree`](https://docs.fedoraproject.org/en-US/fedora/latest/system-administrators-guide/package-management/rpm-ostree). The `rpm-ostree` package manager works by downloading a base image for the system, then overlaying packages over it in a [git](https://en.wikipedia.org/wiki/Git)-like commit tree. When the system is updated, a new base image is downloaded and the overlays will be applied to that new image.
|
||||
|
||||
After the update is complete you will reboot the system into the new deployment. `rpm-ostree` keeps two deployments of the system so that you can easily rollback if something breaks in the new deployment. There is also the option to pin more deployments as needed.

You can also *test* the new generation by switching to it at runtime, but not setting it as the current system generation.

Atomic updating distributions, on the other hand, apply updates in full or not at all. On an atomic distribution, if an error occurs while updating (perhaps due to a power failure), nothing is changed on the system.

For a secure system, you are also expected to have sufficient Linux knowledge to properly set up security for their system such as adopting a [mandatory access control](https://en.wikipedia.org/wiki/Mandatory_access_control) system, setting up [kernel module](https://en.wikipedia.org/wiki/Loadable_kernel_module#Security) blacklists, hardening boot parameters, manipulating [sysctl](https://en.wikipedia.org/wiki/Sysctl) parameters, and knowing what components they need such as [Polkit](https://en.wikipedia.org/wiki/Polkit).

Anyone using the [Arch User Repository (AUR)](https://wiki.archlinux.org/title/Arch_User_Repository) **must** be comfortable auditing PKGBUILDs that they download from that service.

Fortunately, [Wayland compositors](https://en.wikipedia.org/wiki/Wayland_(protocol)#Wayland_compositors) such as those included with [GNOME](https://gnome.org) and [KDE Plasma](https://kde.org) now have good support for Wayland along with some other compositors that use [wlroots](https://gitlab.freedesktop.org/wlroots/wlroots/-/wikis/Projects-which-use-wlroots), (e.g. [Sway](https://swaywm.org)). Some distributions like Fedora and Tumbleweed use it by default, and some others may do so in the future as X11 is in [hard maintenance mode](https://phoronix.com/news/X.Org-Maintenance-Mode-Quickly). If you’re using one of those environments, it is as easy as selecting the “Wayland” session at the desktop display manager ([GDM](https://en.wikipedia.org/wiki/GNOME_Display_Manager), [SDDM](https://en.wikipedia.org/wiki/Simple_Desktop_Display_Manager)).

We recommend **against** using desktop environments or window managers that do not have Wayland support, such as Cinnamon (default on Linux Mint), Pantheon (default on Elementary OS), MATE, Xfce, and i3.

Some Linux distributions (such as [Linux-libre](https://en.wikipedia.org/wiki/Linux-libre)-based or DIY distros) don’t come with the proprietary [microcode](https://en.wikipedia.org/wiki/Microcode) updates which patch critical security vulnerabilities. Some notable examples of these vulnerabilities include [Spectre](https://en.wikipedia.org/wiki/Spectre_(security_vulnerability)), [Meltdown](https://en.wikipedia.org/wiki/Meltdown_(security_vulnerability)), [SSB](https://en.wikipedia.org/wiki/Speculative_Store_Bypass), [Foreshadow](https://en.wikipedia.org/wiki/Foreshadow), [MDS](https://en.wikipedia.org/wiki/Microarchitectural_Data_Sampling), [SWAPGS](https://en.wikipedia.org/wiki/SWAPGS_(security_vulnerability)), and other [hardware vulnerabilities](https://kernel.org/doc/html/latest/admin-guide/hw-vuln/index.html).

We **highly recommend** that you install microcode updates, as they contain important security patches for the CPU which can not be fully mitigated in software alone. Fedora and openSUSE both have the microcode updates applied by default.
