getent queries the system resolver for the hostname - but it's not
the resolver we're interested in. In fact, the hostname-to-be-set
may already exist in DNS (becuase DNS really is a nifty thing and
can do a lot of things which are not that possible with /etc/hosts
alone), in which case getent will "not fail" and vagrant will believe
the hostname had already been set.
Instead, query hostnamectl for the "static" hostname - that's the
one we will be setting, so we're ok IFF hostnamectl returns exactly
what we would be setting.
In order to get a SUSE guest running and installing fine i have added a
correct capability for installing rsync and nfs-client.
I have included SUSE naming fixes as well because SUSe doesnt get
spelled SuSE anymore :).
