When the same SSID is used by two networks, one protected and one unprotected,
ifcfg scripts created by NetworkManager are called "ifcfg-Auto_NAME" and
"ifcfg-Auto_NAME 1".  Init scripts do not like this.

This is done on purpose in src/settings/plugins/ifcfg-rh/writer.c:

  if (g_file_test (ifcfg_name, G_FILE_TEST_EXISTS)) {
         guint32 idx = 0;
         g_free (ifcfg_name);
         while (idx++ < 500) {
                 ifcfg_name = g_strdup_printf ("%s/ifcfg-%s %u", ifcfg_dir,
                                               escaped, idx);
                 if (g_file_test (ifcfg_name, G_FILE_TEST_EXISTS) == FALSE)
                         break;
                 g_free (ifcfg_name);
                 ifcfg_name = NULL;
         }
  }
  g_free (escaped);
