Comment 19 for bug 1348663

Inside an lxc container, bridged via juj-br0 to get an IP address from MAAS, neither "dhclient -r" *nor* "ifdown eth0" cause MAAS to forget the lease.

However if I do ifdown, delete the dhclient leases file and *then* do an ifup the lease is removed and then re-added (with the same ip address of course but I definitely see the removal). I think it's going to be hard for us to fix this outside of the addressable containers story.
