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.

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