No, as far as I know there is no such option in bacula at this time...

Yes, I understand. I usually prefer to do that via LVM snapshots
(*much* faster than full restore).
However, if I need to restore whole machine to previous state from
bacula tape backup, I boot from rescue USB stick (with static
bacula-fd on it), nuke all data (mkfs all partitions is fastest way),
and then do the full restore (note: on full restores, you always have
to watch out to reinitialize the boot loader at the end, or you could
end up with unbootable machine, which means more downtime)

There are alternatives -- you can restore everything to some subdir
like '/RESTORE', and then delete or move all old stuff ('/*', except
'/RESTORE' of course) and then move restored stuff to right locations
- but you should use statically linked tools for that operations or
things will break when /lib and similar directories disappears).
I do that for example if I do not have physical access to the machine
(in which case one has to be very careful :)

I need that very rarely though (I usually test upgrades on virtualized
test instances first) so the booting from USB is not the issue for me,
but I can see your problem (when it is full system we're talking about,
than you can't easily do "rm -rf /" and then run a restore; but you
need to boot from CD or USB or something first which is somewhat
inconvenient)
So such a feature ("accurate restore", eg. nuking all files in
specified restore directory not present in restore fileset) might be
nice, but not nearly cruical (you still need to make your USB recover
stick with bacula anyway in case your machine dies and you need to do
full restore with nothing of the old machine left, and that is the
most of work).
However, if you do such restores very often and think it is important,
you could submit a feature request as described on:
