Just so long as you don't have that mounted at the time, since there's
no attempt to check the filesystem aint in use :-) To be fair, one would
hope that anyone who chose to use a script like this actually realised
enough of what they were doing that it wasn't an issue.

My favourite line in your script has got to be ``print 'All done!
Hopefully your filesystem is not toast.'''

Quite :-)
