I like this.  Would it be worth putting a small writeup
of this in the Developer's Handbook?  Being able to
write programs which can parse and edit rc.conf
is actually quite useful in certain cases.

An analogy for this would be the API that is used
to read/write settings to the Windows registry. 

On a side note, is there any code in sysinstall
that could be reused outside of the sysinstall application
in order to parse rc.conf?
