Comment 5 for bug 1618487

I confirm that even without Sharedscripts config directive, on fuel 9.0 large deployment, logrotate is still broken with errors
error: error creating output file /path/to/file File exists

So this fix to include
  dateext
  dateformat -%Y%m%d-%s
to both /etc/logrotate.conf and /etc/logrotate.d/fuel.nodaily on both fuel master and slave nodes is very much needed.
