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.

Some questions about fedora (self.linux)

Hello. These questions are self-hosting related, but I feel they do partially belong here as they are also about fedora linux in general. I have a server which is currently running Debian. It has an arc GPU, and no matter what I do, video encoding refuses to work. I was thinking I might move it to Fedora, but have some questions first.

How are Fedora's updates? I believe they are about once a year, so how is it to switch between versions? I can deal with annual maintenance, but don't want weird issues causing downtime.
Also about updates, how should I do auto updates on fedora?
I am currently on apparmor. I know seLinux has more features, but I have also heard that it can be annoying to deal with.
I mentioned the arc GPU. Has anyone managed to get video encoding working on it on fedora? If so how?

Edit: also, how is it to move a raid over. It is mdadm raid 5 with ext4. It is VERY important that nothing happens to the data, unfortunately I have not yet implemented a backup, although I do intend to soon.

Fedora has a major update every 6 months, and every version is supported for 2 releases + 1 week (= ~1 year).
Updates have always been pretty painless for me. Most of my problems during updates have come from NVidia drivers (on a laptop), but a fix has always been available from the community.
Fedora has auto-update systemd services for both DNF and RPM-OSTree (more on this later). IIRC it's just enabling a service and maybe editing a config file, but this is easy to search for, so I won't tell you stuff I might not remember.
SELinux mostly just works, and if it doesn't it's probably a bug (if something is a package for Fedora, SELinux should work OOTB. Browse Fedora Magazine for the quirks you need to know how to handle.
I have no experience with ARC GPUs but Fedora might have better support as it tracks the latest kernel release = latest driver (depends on what was actually the issue, of course)

Concerning you RAID, just make sure the installer doesn't touch it and mount it afterwards. You might have to do some kind of "restore" to give the files the needed SELinux metadata. The Discourse forum would probably be a good place to ask.

Now, a bit about DNF vs RPM-OSTree. Fedora with DNF is the standard distro much like most other distros. Use this if the next part doesn't sound useful to you.

RPM-OSTree is used in a new family of distro that work a bit like git for your OS.
Your system runs off an "atomic" image. Atomic means unsplittable in Greek. Everything you change on your system is applied to your atomic image, like a file is added or removed from a git repo.
This is nice because upgrading to the next major version becomes a simple matter of rebasing you changes on top of the new version, and likewise, rolling back (in case of issues) becomes a single command and a reboot.

Fedora IoT is the "Server" edition of the Atomic desktops. Fedora CoreOS is a more "immutable" approach.

Feel free to ask more questions if something doesn't make sense.

If you're interested in fedora atomic desktops, I would check out one of the uBlue projects (you can even switch back to plain old fedora atomic if you want)
