I have been using linux for about 2 years now and I have enjoyed every second of it. What in your opinion is the best package manager the linux community has ever offered to us? dpkg, apt, yum, pacman, xbps, zypp, nix, guix, portage, 0install and other tons of them that are out there.
I don’t have any experience with Nix but I imagine you’d find similar difficulty with that package under Guix. The maven-build-system is in the works but is stuck in development heck.
