small. ISC dhclient was another alternative, but it is an extremely large
program, and it would have been very hard to audit it for correctness.
udhcpc was not all that great of a choice, since it was designed to be small at
all costs, sacrificing correctness when necessary. The code was hard to
follow, and had many quirks. Bounds-checking was rare, type aliasing common,
and state transitions were convoluted. Not all of the client was asynchronous,
and no precautions were taken against conflicting peers. ARP was not used at
all.

However, it was small. With a lot of work, I ripped out the script-calling
mechanisms and replaced them with ifchd requests. Bounds-checking was
