pmount isn't installed with suid root

[anfelor]

Issue description

Apparently the suid hasn't been set for pmount.

$ pmount /dev/sdb1
Error: this program needs to be installed suid root

I would consider this a bug, but it seems that it was done on purpose.
If so, I would appreciate a description of how to mount usb drives then on NixOS.

Steps to reproduce

Install pmount and try to mount a usb drive
This happens both with nix-env installation and system-wide installation.

Technical details

• System: (NixOS: 16.09)
• Nix version: 1.11.4
• Nixpkgs version: 16.09.680.4e14fd5

Ah, great! It works now.

Thank you!

setuidPrograms has been replaced with security.wrappers:

 security.wrappers = {
   pmount.source = "${pkgs.pmount}/bin/pmount"; 
   pumount.source = "${pkgs.pmount}/bin/pumount";
 };
