No argument that this is valuable, but we cannot rely on filesystem
specific solutions.  Similar topic came up a few days ago following
lunch.  It got me thinking of a better way to ensure this kind of thing
does not require home-grown foot protection from cannons.

It should be fairly trivial to automatically backup /etc (and related)
when 'distribution' is run, either intentionally or accidentally (or by
commit mistakes, such as this).
