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!

Removing nix is mostly done by deleting /nix, and removing some systemd services, as well as deleting some nix-related users or groups (iirc nixblkd)

Because almost all of nix happens in /nix it doesn't clutter much of the system.

/nix doesnt work on Fedora Atomic, thats the thing. So it has to be somewhere else.

I still have dozens of strange Nix users left

It's possible to install nix on Fedora Atomic by disabling SELinux and using bind mounts.

disabling SELinux

I hope this is not a serious suggestion?

This needs correct SELinux labels, and not just disabling it.

Dan Walsh is very sad.

It seems the Determinate Nix installer supports Fedora Atomic with SELinux enabled.

supporting SELinux and OSTree based distributions without asking users to make compromises

Edit:

disabling SELinux

I hope this is not a serious suggestion?

Since no nix installer supported SELinux at the time, it was the only way to use nix on Fedora Atomic. With a better option available disabling SELinux is a bad idea indeed.

I didn't disable selinux

It seems the Determinate Nix installer supports Fedora Atomic and SELinux.

On topic:

I really like Nix and home-manager. I've mostly switched to NixOS because it's more convenient for window manager setups than building ublue images imo.

Having to mess with containers for different dev environments and keeping the up to date is imo more annoying than creating a shell.nix

Also being able manage my dorfiles with home-manager and installing software declaratively helps in keeping the system free of clutter.

Why does it work on my machine? I'm on silverblue

[–] boredsquirrel@slrpnk.net 3 points 5 months ago (1 children)

Dont know how they solve it, but /nix is not possible.

Maybe in /var/nix and symlinked or mounted to /nix

[–] Chewy7324@discuss.tchncs.de 1 points 5 months ago

Yes, that's likely the case.

The ahayzen/silverblue-nix guide uses bind mounts from /var/lib/nix to /nix. The latter being created by making / temporarily writeable with chattr +i /.
