Migrating from Arch to GUIX, or, An Exercise in Toe-Dipping

As a friend of GNU, a contributor to the EFF, a rabid follower of Cory Doctorow and RMS, a subscriber of all that is FOSS and the FSF, an all around RJ¹ - and just an insufferable person in general - I've decided that the correct, moral, ethical, right, honorable, just, fair, proper, and applaudable thing to do is move more towards GNU as my choice of OS

Background

GUIX is a package manager that can work on top of any existing flavour of Linux, and indeed can be considered a standalone OS in itself when deployed with either the linux-libre or the hurd kernel².

It can create environments and even docker images from a desired set of packages:

guix pack -f docker gimp inkscape <other>

similar to conda. It also allows you to completely declare your desired system, complete with packages and configurations from a single specification written in Scheme (Guile)⁴, similar to NixOS.

Migrating Arch to GUIX

Arch linux is pretty bare-minimal OS, that installs only what you want without any extra bells and whistles, and since it's my OS of choice on all my machines. I decided I would uninstall all my packages that depend on "pacman" (Arch's default package manager), and install them via "guix" using the "guix-installer" package on AUR⁵ and running `sudo guix-install.sh`

A nice way to find your top-level packages which are not dependencies on others is to run

comm -23 <(pacman -Qqt | sort) <(pacman -Sqg base base-devel | sort)

From this list you can work your way through uninstalling each package `pacman -R <blah>` and installing the guix equivalent `guix install <blah>` (note: no sudo here).

Caveats

There should be no difference in filesystem usage unless you forget to allow guix to download pre-built binaries. I've noticed that some kde packages don't have pre-built binaries, so these might take some time to build locally. I recommend just purging the whole KDE ecosystem if you can (bye bye sweet kdenlive).

Firefox is not available (GNU Icecat is the preferred browser), so this was a package I kept on Arch as I need Firefox. It complained about missing libraries, but you can get around this by running

LD_LIBRARY_PATH=/usr/lib firefox

Afterthoughts

Otherwise, everything is running just fine! At some point I will move to a full GUIX system, but for now, I'm content to keep my Arch packages to the bare minimum and just use GUIX whenever I need to install anything.

Have you taken a look at Nonguix? It seems to offer a firefox distribution.

Just barely related (trigger: the words "friend of GNU")... and forgive me if I've posted this before (getting old...), but once upon a time I recorded song spoofs under the band name 'gdbeatles', and this ("'Till There Was GNU") was one of their hits:
