We want to stop systemd from being added to docker images, because of rpm requiring systemctl.

The problem  is lots of services require systemd because they ship a
unit file and want systemctl reload to happen.  Systemd then triggers a
require for udev and kmod, which docker containers do not need.

rpm -q --whatrequires systemd| wc -l

On rawhide I see 151 packages on my system which require systemd.

We have a couple of options we could add a package called fakesystemd
which provides a /usr/bin/systemctl that does nothing and does a
provides systemd in the specfile.  Then if the user wanted to install
systemd into a container it would need to obsolete the fakesystemd package.

Or we could break out /usr/bin/systemctl into its own package and have
it be smart enough to do nothing if systemd did not exist.
