Actually I think the options specified were fine.  IIRC if you are
root then the permission restoration is the default for tar.  If you
are not root then modern OS configuration won't allow a non-root user
to chown a file to another user and this would fail anyway.  Therefore
the default behavior without the 'p' option is the usual desired
behavior.

On older operating systems especially those based upon SysV you could
chown files to other users.  But that is a less desirable
configuration IMNHO.  (Even though some still preserve that capability
for their legacy.  But I always turn that off on hpux and get a modern
behavior.)
