+====== Using Embedded Ruby to Conditionally Set Template Parameters ======
+As an example, assuming that a server is a dedicated seedbox machine, one would like to switch the TCP congestion protocol to ''lb'' over ''htcp'' or others. The following ERB template branches on the server FQDN and sets the TCP congestion protocol:
+<code>
+<% if @fqdn == "media.home" %>
+net.ipv4.tcp_congestion_control=lp
+<% else %>
+net.ipv4.tcp_congestion_control=htcp
+<% end %>
