Colin Walters c66511d4f9 atomic-host: Stop overriding /etc/udev/rules.d/80-net-setup-link.rules
This bit was cargo culted from the old school Fedora Cloud image, but we have
also been using `net.ifnames=0` on the kernel command line, which ensures that
we get `eth0` as "the" NIC name.  (There's a huge amount of history behind
this and I'm not trying to change that behavior here)

The problem is that those udev rules do *other* things that we do want, such as
ensure that `veth` devices get `NM_CONTROLLED=no`. Without that e.g.
NetworkManager might try to do DHCP on those devices, which is at best slow
since they appear and disappear frequently, and at worst risks the host network
configuration.

For more information, see [RH bz#1503347](https://bugzilla.redhat.com/show_bug.cgi?id=1503347)

# Fedora Atomic Host is the Fedora version of the "Atomic Host" pattern
# from [Project Atomic](http://www.projectatomic.io/).
# This kickstart is used for cloud/virt images, and uses cloud-init
# to bootstrap authentication, just like Fedora Cloud Base. (Also note the
# fedora-atomic-vagrant.ks kickstart inherits from this).
# One very important thing to understand is that this image contains the same
# OSTree commit as will be used on bare metal installations - Fedora Atomic Host
# also has an ISO. One difference though is that cloud-init isn't enabled for
# bare metal. When processing this kickstart then, Anaconda isn't actually
# installing packages - it's just replicating a "pre-assembled" tree from
# rpm-ostree.
# Basically, the `ostreesetup` verb replaces the traditional `%packages`
# section. For example, `rpm-ostree status` can show you the same checksum and
# version from an ISO install and this cloud image - it's the same bits.
