I'm going to make the assumption you already have it installed and configured and working properly..if not then do that...the scope of this howto is just to simply chroot it.
# mkdir -p /usr/chroot/dhcpd
# mkdir -p /usr/chroot/dhcpd/dev
# mkdir -p /usr/chroot/dhcpd/etc
# mkdir -p /usr/chroot/dhcpd/usr/lib
# mkdir -p /usr/chroot/dhcpd/usr/libexec
# mkdir -p /usr/chroot/dhcpd/usr/local/sbin
# mkdir -p /usr/chroot/dhcpd/usr/local/etc
# mkdir -p /usr/chroot/dhcpd/var/db
# mkdir -p /usr/chroot/dhcpd/var/run
# mknod /usr/chroot/dhcpd/dev/null c 2 2
# chown root:sys /chroot/dhcpd/dev/null
# chmod 666 /chroot/dhcpd/dev/null
# BPF="`ls -l /dev/bpf0 | awk '{ print $5; }' | sed -e 's/,//g'`"
# export BPF
# cd /usr/chroot/dhcpd/dev
# mknod bpf0 c $BPF 0
# mknod bpf1 c $BPF 1
# chmod 0600 bpf*
# cp /usr/lib/libc.so.5 /usr/chroot/dhcpd/usr/lib/libc.so.5
# cp /usr/libexec/ld-elf.so.1 /usr/chroot/dhcpd/usr/libexec/ld-elf.so.1
# cp /usr/local/etc/dhcpd.conf /usr/chroot/dhcpd/usr/local/etc/dhcpd.conf
# cp /usr/local/sbin/dhcpd /usr/chroot/dhcpd/usr/local/sbin/dhcpd
# cp /var/db/dhcpd* /usr/chroot/dhcpd/var/db/
Now test it:
# chroot /usr/chroot/dhcpd /usr/local/sbin/dhcpd
Congrats... now just edit your startup file.
