Thanks, Dwight - I'd actually pushed this to my staging branch and a bzr
branch, but then I noticed one thing:

This should be taken from a config file (at least if provided), not
overriden in the template.  So for instance, I was (implicitly) using
lxc-create -t oracle -f /etc/lxc/lxc.conf -n o1
where lxc.conf is:

lxc.network.type=veth
lxc.network.link=lxcbr0
lxc.network.flags=up

but the oracle container was set to lxc.network.link=virbr0.  Since I
didn't have libvirt installed, the resulting container fails to start.
When I switch the link over, it starts beautifully.

I'm not sure how you'll want to do it - just not 

    rm -f $cfg_dir/config

and then only add a network segment if one hasn't already been
specified?

For now I've pushed your patch unchanged onto github.com/hallyn/lxc
branch staging.oct5.1 (and onto
lp:~serge-hallyn/ubuntu/quantal/lxc/lxc-oracle), but that should be
fixed before being merged into the github.com/lxc/lxc staging branch.
