Flip -q (be quiet) into -v (be noisy), making terseness the default
behaviour.

Always go daemon after link_timeout seconds and complete lease
negotiations in the background if necessary. No hanging around in the
foreground for the full 64 seconds waiting for a server to appear.

Log a more relevant message when a default route can't be obtained via
RTM_GET. i.e. "no default route" rather than "No such process".
