Right, I've seen "an LTS set of packages would be nice" as a point before, I agree that it would be good to have.. but I think the communities for this are too small to support it. I've not used Guix, but have used Nix. > I must be missing the point a bit In terms of reproducing how software is built/run? At the risk of starting a flamewar, I believe one of the reasons use of Docker is so popular is how easy it made it to deploy software in a way that you've got confidence it will run the same way. But I'd suggest a point worth considering about Nix/Guix is more that advantages like "reproducible package behaviour" or "straightforward installation rollback" etc. are easy with Guix or Nix, but difficult to get elsewhere (or even benefits you can't get with other tooling).
