In fact I'm talking about https://github.com/NixOS/nixpkgs/issues/16845

Exactly, the actual screenlocker would be installed as a system package, 
I thought it was okay because I noticed something like that was already 
present in xfce.nix, but maybe we can adapt xfce4-session to accept a 
new build input and change it so that it calls the screenlocker in the 
nix store instead of calling the system package.

With regards to slock: maybe we can ask the user to explicitly enable 
the suid like we do when a user tries to install a non-free package?
