On Ubuntu, you can take advantage of Personal Package Archives on Launchpad simply by specifying the user and archive name.  On other apt-based systems this must be the complete entry as it would be seen in the sources.list file.

This is crap but configuration for http scope cannot be both ordered and
merged from map.jinja it seems, see issue #40.

To resolve the occurrence of the below error, a dependency has been added to require the nginx user first be created, either by nginx package installation or explicitly with salt (when installing nginx from source).

* added comment for pillar example
 * removed override releasever variable use for CentOS

* removed override releasever variable use for CentOS

Needed to add repo management because opensuse doesn't have nginx
in default repo

this is needed on archlinux where the pid file is set by systemd
not the nginx.conf file.

In the pillar file you just add
  pid:

an value of 'None' and no pid entry in nginx.conf.
this now works with every None value set in the pillar file

chkconfig was attempting to remove /etc/init.d/nginx when it did not exist.
