I used nixos for a few weeks and then went back to Debian.
* I share the concern of the author on symlinks farm. It is scary! I would like it to be dealt with in the filesystem layer (Plan 9 had a snapshot based filesystem - fossil - years ago). Symlinks have all sorts of weird semantics on different Unix machines.
* Another of my gripe with nixos is that it makes Unix, a single user machine! Sure, packages need not be installed in a user-local way. I may be ignorant of other possibilities here.
* More care for licenses. I still use Debian because they really care for licenses. Last I looked, nixos was in no way close to Debian in terms of documenting the various copyrights and licenses of files pertaining to a package.
Otherwise, Nixos is a great idea and a huge step forward.
