Briefly, a DHCP client needs to be able to both send and receive IP packets before its interface has an IP address. Using the standard 4.4BSD IP stack, the only way a user process (the DHCP client) can receive IP packets is using BPF. I believe Linux has some hooks in its IP stack to work around this. Feel free to provide patches to add a similar facility to the FreeBSD IP stack. >Which leads to the idea of a kernel config option, similar to the one >that lets you set flags for syscons.
