Parabola GNU/Linux-libre user here. On paper, GNU Guix System looks exactly what I want from an operating system. The problem I have with it is the software repository full of severely outdated packages. Heck, last time I checked GNOME was three major versions behind. This is a deal breaker for me. It’s a downside that I don’t see coming up often in discussions.
After having used Parabola GNU/Linux-libre for more than ten years, I seriously considered moving to GNU Guix System. The only thing holding me back is that I saw some seriously out of date packages in the repository. Off the top of my head, GNOME was like three major versions behind. How do you deal with that?
Not much related, but I want to chime in to express my gratitude for what I consider the most underrated piece of software in the FOSS ecosystem. Better known hex editors pale in comparison to wxHexEditor in terms of features and user interface. I suggest you to tweak the colors for better viewing (I can share my configuration file) and to upgrade to the latest unstable revision because many important fixes landed since the last stable version.
