Bug#988236: Likely the best solution

[Kurt Fitzner]

For what it's worth, I concur with this solution.  The lighty-enable-mod 
and -disable-mod helpers are an abstraction layer that certainly 
originated with Debian and may still be unique to Debian (et al).  They 
came into being sometime in 2005-ish.  While, as an abstraction, its 
purpose is to hide the underlying config file mechanics, I can't see the 
underlying mechanism changing any time soon if it hasn't in the last 16 
years.

Upstream lighty has never adopted this abstraction, so I can't see it 
worth the trouble to expand on it now.

I think you've lighted (hah) upon the best solution here.
