Comment 13 for bug 551847

Quoting nurmi:

| As discussed this morning, we don't foresee any problem that would
| come up if this patch were put in place. Neil has looked at the
| patch, and agrees that it will solve this specific problem. In the
| future, several options will likely be explored, ranging from
| modifications to the UEC/EC2 VMs themselves to remove persistent net
| rules, to adding a general notion of 'distro excludes' to euca2ools.
