Comment 2 for bug 1460151

Hm, so you're suggesting that juju overwrite the maas-supplied Apt Configuration for http proxy?

The scenario is, for instance, that the environment already has apt-cacher-ng configured on the network, and I want all of my machines to use that proxy (because, for instance, I have non-MAAS/Juju machines that are already using it and I want to avoid re-downloading of the packages).

Is there a (simple) way to change what MAAS will be providing as Apt Http Proxy?
