C++ isn't the problem.  Devd's size wouldn't be any smaller if I'd =
written it in pure C.  People have sent me patches that move it to pure =
C over time.  Yet, when written in C, the binaries are the same size =
(well, within 10k), and the run-time speed and memory consumption are =
comparable.  Devd was written with the small, embedded system in mind, =
and was always considered to be on the path to being mandatory (you are =
free to write your own devd-like program, if you like btw).

Haven't looked at the dhclient issues surrounding this tread, but C++ =
size and bloat of devd is an argument not supported by the objective =
facts.
