I was just reading about it, it sounds like a pretty cool OS and package manager. Has anyone actually used it?
This is the case for me as well. I tried NixOS this weekend, and even though it has more adoption than Guix, it still does not have 100% coverage of all software I wanted. That said, the packages I did install were pretty up-to-date. I guess NixOS is as close to “critical mass” as we’ve got when it comes to this type of OS. But if I were a wizard devops type person with more time, I’d probably enjoy Guix more.
It’s a bit of a nitpick, but I’d argue there’s more than one critical mass, and NixOS is already there for the purposes of tinkerers and some early adopters. General Linux people are next, and it’s probably not quite there, which is I think what you’re getting at.
Since it’s the frontrunner as you point out, I have high hopes it will make it.
