We want to build images from ostree ref that gets updated "nightly"
but we want consumers of the image to track the two week releases.
This is part of work for ticket: https://pagure.io/releng/issue/6545
* removes the extra ens3 ifcfg that seems to be added
by dracut at some point (cloud base did this in their
ks a year ago in c509863)
* adds net.ifnames=0 to the bootloader line, because
that seems to be necessary to actually disable consistent
device naming
* enables the network service
see https://pagure.io/atomic-wg/issue/174
Due to #1369794 , anaconda cannot currently manipulate sysv
services in F25+. So to work around this, take 'network' out of
the services lines in all kickstarts and instead manipulate
it in the %post section, with chkconfig.
Also remove rsyslog from the Atomic image services line because
it doesn't appear to be included in the OStree tree at present
and so attempting to enable the service breaks Atomic image
compose, see e.g.:
https://kojipkgs.fedoraproject.org//work/tasks/9022/15349022/oz-x86_64.log
also correct the name of the ssh service in fedora-arm-base.ks;
it's sshd not ssh.
