We have the lsb-release package in nixpkgs, but if you run it on NixOS, you get:

LSB Version:	n/a
Distributor ID:	n/a
Description:	(none)
Release:	n/a
Codename:	n/a

It seems like we need a file in /etc/lsb_release for the tool to find. My inclination would be to make a NixOS module that just injects sensible values into that file and to include it unconditionally. Am I missing anything obvious there?

Edit: or we could patch it somehow to just read /etc/os-release, which seems like a better path forward, but less standard.
