statically enabled is bad in general, containers are not a good
reason to enable something for everybody, many if not most people
never will use containers for several reasons and if it because
they use full-virtualization and move machines between different
also non-linux hosts

where i would support something new enabled by default is if
could *replace* something else like LSB network.service while
use it's ifcfg-configurations for backward compatibility and
test out if it really can replace all cases

if i can replace that below i start to be one of the first
production users in a complexer setup (one is the MAC of
the physical card, the other is what it becames before
fetch the IP from the ISP because you need to register
your MAC there, that's the same like MAC cloning
in small soho-routers)


but something hanging around unconfigured please no
