I would suggest submitting it as a root cron job.  But go over the
script very, very carefully to make sure there are no security holes.

One thing to remember about cleanup in scripts--use trap.  E.g.,

  TEMPFILE="/usr/tmp/foo.$$";
  ...
  trap "rm -f $TEMPFILE" 0;

It's useful for many other things, of course, but a very common use for
trap is to specify actions on exit.
