We must dump all pool data to this file to trigger a resync.
Otherwise, confd notices the file hasn't changed and won't
run our python update script.
 
{{range ls "/pool"}}{{$data := json (getv (printf "/pool/%s" .))}}
  {{if $data.ipip}}{{if not $data.disabled}}{{$data.cidr}}{{end}}{{end}}
{{end}}
