     This means that the path to the socket the minion is using is too long. This is
     a system limitation, so the only workaround is to reduce the length of this
     path. This can be done in a couple different ways:
-    
+
     1.  Create your virtualenv in a path that is short enough.
     2.  Edit the :conf_minion:`sock_dir` minion config variable and reduce its
         length. Remember that this path is relative to the value you set in
         :conf_minion:`root_dir`.

     ``NOTE:`` The socket path is limited to 107 characters on Solaris and Linux,
     and 103 characters on BSD-based systems.
