It's easier to figure that out with the coarse granularity of a numbering
scheme than the fine granularity of a dependency scheme. Really.

One possibility is to abstract the dependencies in the makefile, so that you
have your package set up like so (I say, use command syntax to make
parsing easier, and discourage the baroque. If you have multiple entries,
create config-this and config-that files, or just put them in separate
directories):

	/etc/packages/oracle
			config
				depends-on smtp-server nfs-client
				satisfies sql-server
				name oracle
			script
				orasrv -d /oracle

Then in the makefile, you generate an entry:

	sql-server: oracle [anything else that has satisfies sql-server]

	oracle: smtp-server nfs-client
		orasrv -d /oracle

This also allows the config tool to do a static dependency analysis and
tell you "snmp-manager requires snmp-service, aborting".
