To answer this and the other mail. dhcpcd is a per-interface client.
That's why a dhcpcd variable doesn't make sense -- what interface should
it use?

When using ifconfig_xxN, it doesn't matter much what is used to setup
DHCP and it is easy to understand what is supposed to happen if sysinst writes
ifconfig_bge0=dhcp
to /etc/rc.conf. In contrast
ifconfig_bge0=dhcpcd
is more surprising in what it is supposed to do.

It would be nice to be able to do that with dhclient, but alas it is
very bitchy when more than one instance is running.
