This patch is a follow up patch fixing some nits left by the review
25d3ee547176528e86d42eb026c99a134dff9452.
It does:
* Fix the README file to say that the password *must* be encrypted and
the option values *must* be quoted
* Adds Type=oneshot in the upstart service config file so that upstart
will not try to restart the service over and over.
* Enable setu, sete and setpipefail in the dynamic-login script
