In all 5 defconfigs for 1.13.2 FEATURE_IFUPDOWN_EXTERNAL_DHCP is
disabled and UDHCPC is enabled.  So yes, if busybox ifupdown is used
rather than the ifupdown package (and I don't see runtime update
alternatives magic in ifupdown_0.6.8.bb) only udhcpc is going to be a
working client.  It's probably luck then that people either use busybox
or they use not-busybox and some other dhcp client and real ifupdown.
