OK, missed that.  The whole intention of the exercise I describe in
the book is to have a mirrored root file system.  This has been
consistently the most demanded new feature in Vinum.

The way I describe works as well in this situation.

A much better approach, which I'll describe in the next edition of the
book, is to maintain all config files under RCS.  This gives you more
than one backup.
