It might not be the exact answer you're looking for, but you might get
some idea. I run isc-dhcpd inside CBSD jail and CBSD is started after
local_unbound. For most of my needs, CBSD's b_order (short for boot
order) works nicely, so if jail is an option for you, you might consider
having services in jails and then use your jail manager (does jail.conf
boots jails in order they appear in .conf file or is otherwise able to
sort jail startups?) to force jail startup order.
