[Ovirt-devel] [PATCH server] Use DNS SRV records for qpidd on appliance

there really isn't  something like getdomainname in ruby lib?

This assumes that hostname is correctly set - I had reports where this
wasn't the case, hence the following patch for the node:
http://git.et.redhat.com/?p=ovirt-node.git;a=commitdiff;h=378b5f90b01e471cdf19d51fa7e81fa3139f9b80
where all search domains, as defined in resolve.conf, are tried.
Is there equivalent for dig +search option in  Resolve::DNS ?
