It will be possible to do something like that under UX/RT because of
the scoped namespace support, although the command will almost
certainly require specifying a shadow directory. Actually the entire
system will normally be installed with such an overlay for everything
but certain embedded configurations, due to the underlying packages
being treated as immutable except for adding and removing them.
