[Nix-dev] The .nixpkgs/config.nix file and user configuration

[John Ramsden]

I've been looking for some information about how exactly the 
$HOME/.nixpkgs/config.nix file works. How exactly is it intended to be 
used? Up until now I've been managing my entire system from /etc/nixos, 
but it would be nice to have a place where I can add something that 
happens only to a single user. For example, setting up dotfiles, or use 
our services. Can the config.nix file be used for that? Is it 
effectively a /etc/nixos/configuration.nix that is intended to be used 
for a single user?

I have found little bits of information about it here and there, for 
example in the nix pills. but nothing that really explains what it is 
used for in detail. Could someone point me where I can find this 
information?
