[q#7: Avoid dhcp: This one I was wondering what the heck was the author thinking? The answer to dhcp requests arrives in milliseconds (unless there's something terribly wrong with your system) and it allows for much more flexibility.

[q#7: On my systems it takes sometimes a few seconds to get an address, especially wirelessly. If it fails to get an address (for whatever reason), it may take 30 seconds or so before it gives up. Depending on the OS/Distro, if these task are done serially that can be a significant slowdown.

To me, the biggest speed-up is for most of these tasks to be done in parallel - thus our case of a failed dhcp request wouldn't matter.

If you are using something like ifplugd then this isn't an issue
