CVS is top for /etc management. (Score 1)

Why not CVS?

I have used CVS for /etc of my linux boxes since 2000. It works very well.
It can manage most of your change history for /etc and make them recoverable.
It can even help you with ``cvs diff'' when your /etc is compromised by crackers.

One annoying point of CVS for /etc is its invasive architecture.
It always creates CVS/{Entires,Root,Repository}. This affects some app, so you
need to teach CVS not to handle some files/directories.

If you use non-invasive revision-control system (like SVK),
such problem might be avoidable. But I have not enough experience with it yet.
