Workaround for include being defined too early

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

Adding default include for 'sites-enabled' dir

Resolve missing dependency for nginx home dir.

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).

Initial commit of SPM FORMULA

Fix for incorrect pkg repo base url on Amazon Linux on EC2

* removed override releasever variable use for CentOS

Added nginx.ng.certificates state.

RedHat uses /var/run, not /run

Separate 'dir' into 'available_dir' and 'enabled_dir'

Add support for Arch Linux

Add nginx repo for RedHat family

Fix nginx config on systemd

Added opensuse support

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

Moved entirely to ubuntu's ppa

added test for value None, to be an absent value

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

Minor bugfix and updated pillar.example
