The idea is to switch the default in the code at some point, so then -Z will be needed to get back to the original behavior. The idea is that by having both flags a distribution may choose to decide now what behavior they want and use the relative flag. Then even if we change the default their configuration will not "break". Simo. -- Simo Sorce * Red Hat, Inc * New York
