1. Create an external fact with key "owner" with value of your name, or your team
   1. tips:
   2. you want to create /etc/facter/facts.d/owner
   3. use a puppet file resource, or try using $modulepath/facts.d/owner
2. Add a file "/etc/role" with choice of value of "web", "data", or "compute"
   1. use a puppet file resource to create the file
3. Write a custom fact or code external fact to produce "role" fact
   1. One way of doing the custom fact, which should live in $modulepath/lib/facter/role.rb:

   • require 'facter'
     Facter.add("role") do
       setcode do
          %x{cat /etc/role}.chomp
       end
     end
     

Using the facts

1. facter -p
2. Use the facts as variables to populate motd
3. Remember that facts are top-scope, so you will want $::role and $::owner
