Not in "production" but I use it on my personal laptop and desktop. I wanted to learn a scheme and I figured what better way than to dedicate all of my home computing time to configuring a system and crying myself to sleep trying to build firefox on it.

If you get firefox working, please share your definition on the nonguix[0] repo. Lack of Firefox is what is currently holding me back from installing Guix on hardware. I don't know anything about package building, but I'd be happy to help collaborate if you need it.

So two things:

1. I believe icecat is going to update pretty soon to version 68 to track with the latest esr, so perhaps in a week or so please check the main channel for an icecat version that should work with most, if not all, up to date extensions.

2. If I do get Firefox built and packaged then I’ll be more than happy to add it to the nonguix channel. Though I’m strongly considering just creating an unofficial icecat that keeps up with the latest version of Firefox like icecat on windows does. We’ll see what happens after these tears dry.

Icecat is really just a set of scripts to strip out branding from Firefox and packages it with gnu shit, though the gnuzilla project provides the esr version for convenience.

I use x11docker to run a recent firefox on Guix for now. https://github.com/mviereck/x11docker

Bitcoin. All bitcoin binary releases going forward are compiled with Guix for reproducibility. (The Bitcoin Core team previously used an in-house guix-like thing that they developed themselves. They switched to guix this year.)

Hey, that's awesome. Can you share some links on it?

I'm using it on my fileserver, swimmingly. I build the image on my desktop and then swap the boot drive and restart. It replaced some Arch linux hack scripts I was using to do the same, and with much less external tooling.

I wrote up a general guide here along the way: https://gitlab.com/rendaw/blog/blob/master/how_to_guix_for_t...
