Many of my servers are remote and if there is an issue with a port, I still need a way into the system other than driving for hours.  This works.  Sshd is started early in the sequence and I can at least ssh into the server.  It won’t help though if there is a syntax error in /etc/rc.conf.  Those are pretty much fatal.

This technique works.  But if you use it, then before you reboot,
remember to run "rcorder /etc/rc.d/* /usr/local/etc/rc.d/*" and make
sure there aren't any errors about "Circular dependency".  If there
are, then the service startup order is almost guaranteed to be
something you don't want.
