This is a change with the potential to confuse admins temporarily, but I
think we should do it.  Experience has shown me that while using inotify
sounds nice, in practice, it ends up being unpredictable.  Notably it
makes it impossible to apply changes to multiple files without
transiently exposing half-done configuration.

This logic sounds fairly sane though.
