      If that takes a long time and eventually fails with erors like:

      ... that is because the [howto/ipsec](howto/ipsec) tunnels between the nodes are
      failing. Make sure Puppet has run across the cluster (step 10
      above) and see [howto/ipsec](howto/ipsec) for further diagnostics. For example,
      the above would be fixed with:
 
-        ssh fsn-node-03.torproject.org "puppet agent -t; service ipsec reload"
-        ssh fsn-node-06.torproject.org "puppet agent -t; service ipsec reload; ipsec up gnt-fsn-be::fsn-node-03"
+         ssh fsn-node-03.torproject.org "puppet agent -t; service ipsec reload"
