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.

the debian package installs the nginx service just fine, but the extra
fifo->syslog functionality would be nice to have under debian as well.

This reverts commit f6ba9ddb59.

the nginx.ng formula is only compatible with the upcoming feature
release, as noted here:

https://github.com/saltstack-formulas/nginx-formula#nginxng

This argument is only currently available in develop, and thus does not
belong in this formula at this time.

If upstart is used, add symlink: /etc/init.d/nginx -> /lib/init/upstart-job
