Handy script to prepare a bare Digital Ocean droplet for Rails deployed via Capistrano

	#! /bin/bash
	# this is a useful little script to setup a rails user, with postgresql, and nginx version of Phusion Passenger on a Digital Ocean droplet
	# Once run it's ready to recieve a Capistrano deployment.
	# The best way to run it is ssh root@my_do_host 'bash -s' < digital-ocean-rails.sh
	set -e -x # die on the first error and send stdout to /var/log/syslog
	#create a password and save it
	PWD=$(cat /dev/urandom \| tr -dc 'a-zA-Z0-9' \| fold -w 20 \| head -n 1)
	mkdir -p passwords
	echo "rails,$PWD" >> passwords/users.txt
	#create a user called rails and allow them to sudo without a password
