Helmut, I'm not sure I follow you here. udhcpc itself is provided by
bysybox. There's no udhcpc without busybox. udhcpc package is just a
set of support files for busybox's udhcpc applet. This is exactly why
I implemented it this way in the dhcp script: we're absolutely sure
busybox implementations of awk and ip are always here, since without
these there would be udhcpc.

No, as far as I understand. B/c udhcpc package lacks the main binary
