* The README.md doesn't metion an EPEL requirement, however it's needed
for installing python-boto on RHEL. Add it to the list of requirements.
* Some gramatical errors were fixed.
* The ``system.yml`` install timeout (10 minutes) is cutting things aweful
close, esp. since it's dependent on both networking and external
services. Double it to head-off possible future headaches.
