If templates are used, as described above, fcopy will copy the file each time,
even if nothing has changed. The only way to do it correctly would be copying
the template to some temporary file, then running {pre,post}inst on this file,
then do the diff ... However, the scripts might have sideeffects, such as
restarting a service. And, IMHO, it is this particular effect why one would not
want fcopy to do its job again and again, if the template had not been changed.
Still, I see no reason why this option has to be removed - using templates and
the -P option is probably the most advanced use of fcopy today, and those using
it should be aware of the fact that changes to variables are not detected by
fcopy.
