From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

If the kernel is available in a COPR or another third party repo, you can just do a little swapping with rpm-ostree: https://github.com/openshift/os/blob/master/docs/faq.md#q-how-do-i-replace-the-current-kernel-with-kernel-rt-or-a-new-kernel-version-in-rhcos
Edit: Just in case this is the project you’re using, here’s specific install instructions for Fedora Silverblue: https://github.com/linux-surface/linux-surface/wiki/Installation-and-Setup#fedora-silverblue
Seems a bit too complicated for me, even if it probably ain’t.
But I’d probably use it if one day I break my Fedora workstation install.
Oh it’s definitely over-complicated, and contrary to what others say here, Silverblue can definitely have some very difficult to troubleshoot problems (especially when using things outside the direct Fedora ecosystem), which are greatly worsened by rpm-ostree taking 15 years to do anything despite sharing code with the supposedly lighting-quick dnf5. For servers, rpm-ostree is great (it’s in all of RH k8s offerings, see RHCOS), but on desktops, there’s definitely a good reason why RH has to apparent offering and Fedora calls theirs “emerging”. Still miles better than having an unbootable system after updating.
oh, the 15 years to do anything is true, i know when my system is updating in the background just from the sound of my laptop fan lol, but they do a 3-way merge using the remote image, your overlays and your /etc, so it's a intensive process i guess
