Is this a bad > idea? Are changes to this file more predictable than I am supposing? There are a number of files that will change depending on system activity and that's one of them. Lots of the files in /var/log will also change (messages, dmesg, boot.log, wtmp, you get the idea). prelink is run once a day via the system crontab and its control file /etc/cron.daily/prelink. The cache will change if system libraries are updated via yum/rpm or you build something that adds libraries to the normal system directories. This is controlled by /etc/prelink.conf. ---------------------------------------------------------------------- - Rick Stevens, Principal Engineer rstevens@xxxxxxxxxxxx - - CDN Systems, Internap, Inc. http://www.internap.com - - - - Time: Nature's way of keeping everything from happening at once. - ---------------------------------------------------------------------- -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
