I really like the idea of NixOS and Guix and tried NixOS for half a year on my laptop. Then I changed back to ordinary package based distributions. (Arch, Debian and Gentoo) The issue with NixOS for me was probably quality control. When I did an update and instead of fetching the files from the binary cache it starts to build stuff on its own, I could be reasonably sure that some build error happens. Coupled with sparse documentation, I was very often at a loss at how to fix it and just had to remove the package for a while and try again a couple of days later. Another point is NixOSes path mangling... Do we really need that? Can we not try to use namespaces and OverlayFS etc. to let each process assume it has a normal FHS file-hierachy while in real its 'root' is cobbled together from multiple package installation directories? Instead of patching the paths of every package, letting the kernel do the path calculations seems to be less intrusive.
