I've asked -ports before whether it is suitable to let ports startup scripts
honor /etc/rc.conf{,.local} settings by sourcing /etc/defaults/rc.conf and
then running a source_rc_confs (or whatever is appropriate).
This could be a solution to your problem - modify the ports' startup scripts
to honor rc.conf options, then put appropriate enable/disable options
in each machine's /etc/rc.conf or /etc/rc.conf.local.
Attached is an example - a modification of the databases/mysql323-server
port's startup script to honor a couple of mysqld_* variables from
the RC script scheme.
This approach has the disadvantage that the ports' startup scripts will
have to be modified if the base system startup mechanism changes, or
at least when the base system /etc/{defaults}/rc.conf{.local} parsing
mechanism changes.
G'luck,
Peter
