Most variants of the Linux Router Project (LRP) use either dhclient or
dhcpcd; in the variant I've developed, I embedded dhcpcd into the base
system and it works well.  It's much simpler than dhclient, but
dhclient is more powerful; however, dhclient appears to have at least
SOME dependency on kernel version, though I'm not sure why - it just
stopped working when I upgraded the kernel until I upgraded dhclient
to a newer version....

In normal situations, both work quite well.
