So yes, X11FLAVOUR does change the base build in that one place.

In addition to that, I've spent a bit of time on it today, and
etcupdate(8)'s mechanism is _not_ the way to go.  It's far from robust,
and notably won't deal with a read-only source tree.

Any other opinion on that?  That would avoid generating the rc.d scripts
and solve the problem Once and For All, just as we should drop a big ice
block into the ocean to solve global warming.

The one trouble with generating postinstall(8) is that src/Makefile
invokes the file in the source tree rather than the generated one, but
that can be changed easily enough.
