I want to make sure the uuidd daemon is shutdown before removing
the package.  Since the uuidd daemon is provided by the uuid-runtime
package, and I *know* exactly where it is, and I ***don't*** want the
script to be confused by some other pathname being used by the local
administrator, I specify an explicit pathname.  In addition, given the
explicit test to make sure /usr/sbin/uuidd exists, it seems non-sensical
to remove the prepended path.
