You're right, but I think those who are thinking about this procedure 
know that you copying the root filesystem from one drive
to another, therefore by the very nature of that operation you have a
backup.   :-)

I guess the disclaimer should be ...

***************************************************************************
  DON'T FORMAT, MKFS, OR DESTROY YOUR ORIGINAL ROOT FILESYSTEM UNTIL YOU 
  VERIFY THE NEW ONE ACTUALLY WORKS AND EVERYTHING YOU WANT IS THERE!
***************************************************************************

Yes, folks even the best of us goof once and a while.  I remember helping
a good friend of mine swap some HD's around, while I was at her
console (su'd as root) I decided to re-mkfs the slice 2 on the second
drive (for those that don't know it's /dev/rfp012).  Well as things go in
those intense 'hacking' sessions... a slip up of one little number and POOF!  
Well I hate to admit it (and now as she is probably reading this, she's 
rolling in her seat ...) I typed:

# mkfs /dev/rfp002

Tick... tick... tick.  Aborting the procedure prematurely, but too late
to save anything ... And feeling very embarrased, as well as very
much responsible -- I non-chelantly [sic] said, "Do you have a recent
backup of your root filesystem?"  Of course I was handled the 90+ 
diskettes.  [I guess that's better than most UNIXpc'ers]  Two hours and
then some later, things were back to some semblance ...

The moral of the story is ... BACKUP, IT'S WORTH THE EFFORT!
