Not quite - bpf is potentially dangerous where a sysadmin is inexperienced. On a system with a generic kernel and no source on it, it may be fairly difficult to get a kernel with bpf onto the system. Where there is an experienced admin, this becomes less of an issue. I am not trying to stop DHCP being added to the tree. It may even be necessary to use bpf initially, but there must be a more elegant way - having a quick look around - it would be a good idea to look at the code which already exists in libstand (/usr/src/lib/libstand/bootp.c). I haven't had an exhaustive look through the code, but this should give the necessary material to work out another way of doing things.
