The following command should be portable even to older hosts:

find DIR -exec chown user {} ';'

That's the typical behavior, when tar is invoked by root.  In some
Unix implementations tar has an -o option to disable this, but -o has
a different meaning with GNU tar.  So it is a bit of a portability
problem.

    The following command should be portable even to older hosts:

    find DIR -exec chown user {} ';'

I installed changes based on that--could you possibly check them?
