Hi all,

Here are the changes I was referring to in my previous email thread -
these changes make the ubuntu templates aware of squid-deb-proxy
servers visible to the host.

https://github.com/lxc/lxc/pull/134

squid-deb-proxy uses avahi to advertise itself, and so installing
squid-deb-proxy-client on the LXC host lets apt autodetect proxy
settings. With this path the proxy settings are consumed by LXC when
both debootstrapping a new image and inside the container itself.

This makes deploying similar environments (on a development machine
for example, in a CI lab, or for example using juju) *much* faster.
One could achieve similar results by setting APT_PROXY or HTTP_PROXY
when running lxc-create, but the advantage of this patch is that it's
completely automatic.

The cost for people not using squid-deb-proxy is negligible, this
patch therefore adds the hook to the default ubuntu and ubuntu-cloud
templates.

Note: this requires "dbus," to be added to the
/etc/apparmor.d/abstractions/lxc/start-container apparmor profile as
Stephane suggested in the previous thread (if not using the PPA
packages).


Hope this can be as useful for other people as it has been for me so far,

- - Chris
