i use interface renaming on many systems and have not run into problems
with it.  however, i don't use local_unbound, and also don't tend to
rename external or vlan interfaces.

in /etc/syslog.conf, there is a commented example of using syslogd to
write boot messages to /var/log/console.log.  i suggest enabling this,
which will make it easier to see where things are failing.

interface renaming happens very early (before the interface is brought
up) so it usually shouldn't cause any problems, but the output from the
local_unbound startup script would make it easier to see what's going on.
