It's hopefully still better for most virtual machine use cases, as it
will not write out config to disk at every boot and not use MAC
addresses, which can change from boot-to-boot on some boxes.
With the old model we've seen virtual machines with 1000s of entries
in the rules files created by just rebooting them. :)
