Yes of course, but you need to do it via the package manager. You can't "sudo make install". If you build your own software and want to install it system wide, you need to flatpack/brew it or run it in a docker container.

(obviously you can modify the filesystem if you really really really want to).

Bazzite is gaming oriented version of Fedora CoreOs. There are many different versions. I am running bluefin.

I've tried a lot of desktop linux distros, and to be honest, immutable linux feels like the future. Anything you do can simply be rolled back. Break something? Just roll it back.

And if you run something like Bazzite, but want to try out Bluefin-Dx which is developer oriented, then you can rebase your existing installation. If you don't like it, just revert back to Bazzite with a single command.

However, it's desktop oriented. Don't run CoreOs on a server.
