Comment 22 for bug 1348663

I've had it confirmed that the leases file is authoritative, not the MAAS dhcplease database table - so my previous assertions about dhcp release from inspecting the database are flawed.

However, from investigation it seems that neither an lxc-stop from outside the container, nor a "halt" from inside the container, cause a dhcp release. An explicit "ifdown" from inside the container *does*. So it seems like the shutdown sequence does not do an "ifdown". Investigating further. (To see if we *should* be seeing this as Stephane asserted, and if so why it isn't happening, if not to see what it would take for us to add it to the shutdown.)
