Rudder

After installing a SLES12 server, I didn't have any reports (and it didn't self healed)
Logs says:

in the logs, we see that rsyslog is restarted before password are correctly propagated

rsyslog is then again restarted by agent

but it still doesn't log (in /varlog/messages, nor in webapp
Logs are there in /var/log/rudder/reports/all.log

restarting rsyslog solves the issue

In Rudder init i get

cf-agent -b propagatePromises,install_rsyslogd,root_component_check
/var/rudder/ncf/common/30_generic_methods/file_from_template_jinja2.cf:193:69: error: Unknown function
      "state_dumped" expression => dumpdatastate("${datastate_file}");
                                                                    ^
2017-04-14T09:57:21+0000    error: There are syntax errors in policy files

Real cause is on my box, I have a cfengine 3.6.1 preinstalled, so rudder-init didn't call the right cf-agent
