I have no knowledge on DHCP servers, so I won't comment on that.
But I find the argument against Busybox that it tried to "bite off
more than they can chew", as you put it a compelling one.
Recently suckless developers explained why existing core-utils and
linux-utils aren't properly done and why they are working on their own
solutions. They specifically mention Busybox and what (from their
point of view) is wrong with it. Check it out, it's an awesome watch:
If you are just interested on Busybox/Toybox/Etc problems and the
solution (sbase), it's on 11:08.
And they do talk about their sdhcp project on the video too, but I
didn't look much into it.
