CONFIG_IFUPDOWN_UDHCPC_CMD_OPTIONS was set to '-n' which means
"Exit with failure if lease cannot be immediately negotiated."
What we'd rather want is for udhcpc to continue to run until a lease can

server is not reachable for a few seconds during system boot, and end up
having a system that is permanently without an IP address.
