Static interfaces are still configured on the fly as we add them, but
discussions on the mailing list have suggested that we need to have finer
control over bringing up dhcp interfaces.
The default hook just runs all the requested dhclients in parallel and waits
for them to all return. If you need something more complicated than this, or
need to have more control over bringing interfaces up, you will probably need
to override some stuff in the 40network hook.
