Hello, After last glibc update I've noticed (in fact tripwire noticed) that something has changed some executable files on my system e.x.: "/usr/sbin/acpid" "/usr/sbin/alternatives" "/usr/sbin/anacron" "/usr/sbin/apmd" "/usr/sbin/atd" and many others. I've checked md5sum of this files on other FC1 systems and I was shocked! At EVERY system this files have different md5sum, but rpm -v rpm_package doesn't report any changes in MD5! Not executable files have the same sum. I think it's connected with somethink prelink but I'm not 100% sure. Could someone explain me it? Best regards Piotr
