Wesley Aptekar-Cassels has been using NixOS on his main laptop for ~3 years and he’s ready to talk about it:

I don’t think that NixOS is the future, but I do absolutely think that the ideas in it are, so I want to write about what I think it gets right and what it gets wrong, in the hopes that other projects can take note. As such, this post will not assume knowledge of NixOS — if you’ve used NixOS significantly, there probably isn’t anything new in here for you.
