On the shortlist of things to try on my new laptop has been Guix. I have been using Guix on my rsnapshot-based backup server since 2018, and experimented using it on a second laptop but never on my primary daily work machine. The main difference with Guix for me, compared to Debian (or Trisquel), is that Guix follows a rolling release model, even though they prepare stable versioned installation images once in a while. It seems the trend for operating system software releases is to either following a Long-Term-Support approach or adopt a rolling approach. Historically I have found that the rolling release approach, such as following Debian testing, has lead to unreliable systems, since little focus was given to system integration stability. This probably changed in the last 10 years or so, and today add-on systems like Homebrew on macOS gives me access to modern releases of free software easily. While I am likely to stay with LTS releases of GNU/Linux on many systems, the experience with rolling Guix (with unattended-upgrades from a cron job to pull in new code continously) on my backup servers has been smooth: no need for re-installation or debugging of installations for over four years!
I tried the Guix 1.4 rc2 installation image on top of my previous Trisquel 11 installation; following the guided Guix installation menus was simple. I installed using wired network, since the WiFi dongle I had did not automatically become available. I put the Guix system on a separate partition, that I left empty when I installed Trisquel, and mounted the same /home that I used for Trisquel. Everything booted fine, and while I had some issues doing guix pull followed by guix system reconfigure /etc/config.scm I eventually got it working by using --allow-downgrade once. I believe this was a symptom of using a release candidate installation image. Guix did not auto-detect Trisquel or set up a Grub boot menu for it, and I have been unable to come up with the right Guix bootloader magic to add a Trisquel boot item again. Fortunately, the EFI boot choser allows me to boot Trisquel again.
Guix 1.4 uses Linux-libre 6.0 which is newer than Trisquel 11’s Linux-libre 5.15. The WiFi dongle worked automatically once the system was installed. I will continue to tweak the default system configuration that was generated, it seems a standard GNOME installation does not include Evolution on Guix. Everything else I have tested works fine, including closing the lid and suspend and then resume, however the builtin webcam has a distorted image which does not happen on Trisquel. All in all, it seems the resulting system would be usable enough for me. I will be switching between Trisquel and Guix, but expect to spend most of time for daily work within Trisquel because it gives me the stable Debian-like environment that I’ve been used to for ~20 years. Sharing the same /home between Trisquel and Guix may have been a mistake: GNOME handles this badly, and the dock will only contain the lowest-common-denominator of available applications, with the rest removed permanently.
Not to complain or criticize, and rather a positive advertisement:
the advent of debian continuous integration and associated policies for migrations made debian testing a rather nice place for a rolling release in the last few years (i’d say since 2020). The quality of the whole is incomparably better then before bullseye.
Good point — yes, perhaps what was missing was reliable system integration testing to make rolling releases more stable. Settings expectations also helps, I don’t think Debian testing is really advertised as a rolling distribution intended for end-users? It doesn’t provide security support. OTOH, I’m not sure how well security support works for Guix or Homebrew today either.
