Because for 'realm join' we need to do part of the work before actually doing the join post-install. In particular, before the install starts we need discover what kind of domain we're dealing with so that realmd can tell us which packages need to be added to the install set.
This is important because we cannot rely on PackageKit or even the package install sources during post-install.
Are there so many realmd-related packages that this is a real concern?
