We also have busybox-minimal.config, so I've added it there as well and applied, thanks.

The current behavior for busybox' udhcpc is to terminate if no lease is obtained at start up. Therefore no address is acquired if the link is established afterwards. By setting the -b flag udhcpc will background allowing the link to be established at any time.
