Eelco Dolstra 29027fd1e1 Rewrite ‘with pkgs.lib’ -> ‘with lib’
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.

An optional, additional listening port number for peers. Incoming

handshake, described in this document (external link):
http://haproxy.1wt.eu/download/1.5/doc/proxy-protocol.txt
The PROXY Protocol is a popular method used by elastic load balancing
service providers such as Amazon, to identify the true IP address and
port number of external incoming connections.
In addition to enabling this setting, it will also be required to
use your provider-specific control panel or administrative web page
to configure your server instance to receive PROXY Protocol handshakes,
and also to restrict access to your instance to the Elastic Load Balancer.
