Some salt states I'm putting out there for others to learn from and use.
This state sets up nginx using the nginx-extras package from DotDeb.
It also enforces the file /etc/nginx/snippets/ciscodude.rewrites.conf which gets included by two virtualhosts.
This state sets up the observium_agent script and its prereq's.
dnsdist is an amazing DNS load balancer. This sets it up in front of some recursors.
This sets up powerdns recursor or authoritative server.
This state sets up the official deb.torproject.org repo and installs the stable version of tor.
This state sets up the UBNT Unifi Controller (Stable) based on instructions from UBNT Help
