[thanks for the additional details.  For now, I'm just Cc'ing
 the list.  Please retain the Cc in the future, so anyone else
 with the same problem can find this discussion.  This is relatively
 low priority, since very few people care about systems configured to
 allow regular users to use chown.  If you don't hear back from someone
 after a couple weeks, please ping the mailing list. ]
