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.

How to install Nix on Fedora Silverblue (julianhofer.eu)

Today, I wanted to have another go with nix. Previously I just read about it and didn't do anything for a couple of months. Now, I installed nix package manager with very few lines of code and two more to install many packages as described in his post. Installation was very fast on my banana laptop. Until now I used distrobox but I always wondered which distro/ package manager to use. What's your experience with it? For now, I'll test it. It's super easy to use. It may not be straight forward to a linux newcomer but if you know what you want, e.g. ffmpeg you can just add it with home-manager edit and install it with home-manager switch. So far, I love it!

Until now I used distrobox but I always wondered which distro/ package manager to use. What’s your experience with it?

The answers found below this post resonate with my own experiences.

I do have a question: When you run the sestatus command in the terminal, what string/description is found corresponding to "Current mode"?

[–] GravitySpoiled@lemmy.ml 3 points 5 months ago* (last edited 5 months ago) (1 children)

$ sestatus SELinux status: enabled SELinuxfs mount: /sys/fs/selinux SELinux root directory: /etc/selinux Loaded policy name: targeted Current mode: enforcing Mode from config file: enforcing Policy MLS status: enabled Policy deny_unknown status: allowed Memory protection checking: actual (secure) Max kernel policy version: 33

Thank you for the response!

Current mode: enforcing

This is pretty interesting. If I recall correctly, installing Nix onto Silverblue came with the caveat that SELinux' enforcing mode had to be turned off. But, your terminal output tells another story. I wonder what's up.

FWIW, I had lost interest in installing Nix on Fedora Silverblue for this very reason. However, I might have to revisit my stance on this. Once again, thank you (for reinvigorating my interest in Nix)!

I'd like to know if it works for you now. I only ran the commands from the post and everything worked ootb

That's probably why I gave up on it back then as well

Aight. Let's give it a go:

Terminal interaction

Well..., for some reason it didn't work. FWIW, I'm on the bluefin-dx-main-userns-hardened image as provided by secureblue.

Yeah I noticed that line as well. But, I'm a bit pessimistic that it will not be solved. Btw, what's the image you're on?

Boring silverblue 40

[–] poki@discuss.online 2 points 4 months ago* (last edited 4 months ago)

Interesting!

So, I guess that at least one of the following 'transitions' is 'blameworthy':

Silverblue -> uBlue Silverblue
uBlue Silverblue -> Bluefin-DX
Bluefin-DX -> secureblue

I guess I'll pass out on it for now. Thank you though!

The source of the determinate nix installer has some mentions of SELinux. E.g. they have an .fc file, but I really don't know anything about SELinux.
