ISTM it's a bug and should be reported on both CentOS and RH tracking systems. Two errors are apparent. One may be difficult to correct. As you originally discovered, the user ID is being change during execution of the command to change a group. And it is using the ID from the symbolic link owner, as you later noticed. The 2nd bug is a recursion into the original directory via the symbolic link when dereference is not suppressed. IMO, recursion should not occur, but I know from a programming background that it takes a little foresight, thought and intense effort to avoid this sort of trap. As an afterthought, how valid is it to have user control files that are supposed to be contained in an "invisible" directory in the user's $HOME? This presents a "non-standard" structure that offers increased opportunities for mishaps of various types. -- Bill _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
