The resouce should not be started before the booth daemon is ready. We
suggest to configure an ordering constraint for the booth daemon and the
managed resources by that ticket. That being said, if the ticket is in
the CIB but booth daemon has not been started, the resources would not
be started.

Currently when all of the initialization (including loading the new
ticket information) finished, booth should be regarded as ready. So if
you encounter some problem here, I guess we should improve the RA to
better reflect the booth startup status, but not moving the
initialization order, since it may introduce other regression as we have
encountered before;)
