I think calling this an "unusual case" is the root cause of the difference
in viewpoints here.

I *do* appreciate your development work on this. I just want to help you
understand an important segment of the "we" you mentioned before. This way
of doing things isn't merely old-fashioned -- it's got concrete advantages
which continue to be important to Linux as it moves forward.

I don't mind using dedicated command line tools to accomplish tasks -- I'm
fine with using chkconfig to manipulate runlevels, for example -- but the
problem with adding a bunch more of these sorts of thing is that each one
has its own new interface to learn (and relearn if you only do it
infrequently). A key=value config file, on the other hand, can be understood
immediately (particularly with decent comments).

And, you can fix it with any old rescue environment -- no need for fancy
tools. In the real world, that's *huge*.
