#If populating MAAS DNS with domains, all domains get added to the search order.
#Resolv.conf only supports 6, so if you have more 6 domains entered, nothing after the 6th gets resolved

#Also, juju for some reason is doing an alpha sort on domain, which in most cases (and in the case of http://launchpad.net/opm) puts
#the MAAS domain near the end, which is past the 6th domain.

#This function will go through all machines and containers in a model and set a given search order, or
#if used without arguments will set the maas domain as the only entry in dns-search
