What you say?: bash-2.05b$ su Password: bolivia# cp /usr/sbin/cron /home/wmoran/. bolivia# cp /home/wmoran/cron /usr/sbin/. cp: /usr/sbin/./cron: Text file busy bolivia# Notice that /usr/sbin/cron is in use (because my system is running normally) I can copy _from_ that file, but I can not overwrite it. Apparenlty, nobody who is claiming this has _tried_ it. Try it yourself and see. You can _not_ replace programs that have their Text section in use (i.e. the code) because the demand pager has that area of the file locked. -- Bill Moran Potential Technologies http://www.potentialtech.com _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
