Not for me (BIOS clock set to UTC) : % uname -a FreeBSD q.gid0.org 9.0-CURRENT FreeBSD 9.0-CURRENT #0 r220114: Mon Mar 28 23:42:11 CEST 2011 r...@q.gid0.org:/usr/obj/usr/src/sys/QUAD amd64 % date mar 29 mar 2011 00:41:41 CEST % uptime 0:41 up 30 mins, 3 users, load averages: 0,06 0,06 0,07 % ls -l /etc/localtime lrwxr-xr-x 1 root wheel 32 29 jui 2008 /etc/localtime@ -> /usr/share/zoneinfo/Europe/Paris % mount tank/freebsd on / (zfs, local, noatime, nfsv4acls) [...] tank/freebsd/usr on /usr (zfs, local, noatime, nfsv4acls) [...] % grep -i regents /var/log/messages Mar 29 00:12:08 q kernel: The Regents of the University of California. All rights reserved. % tail -n 1 /var/log/messages Mar 29 00:12:08 q kernel: kbd0 at ukbd0 I don't think this content is added to /var/log/messages during boot, because the kernel doesn't have access to the log file (and if /usr is not mounted, neither is /var). I thought the kernel messages were saved in memory (system message buffer), and only after boot (and filesystems mounted, and syslogd started) were they dumped to a file. -- Olivier Smedts _ ASCII ribbon campaign ( ) e-mail: oliv...@gid0.org - against HTML email & vCards X www: http://www.gid0.org - against proprietary attachments / \ "Il y a seulement 10 sortes de gens dans le monde : ceux qui comprennent le binaire, et ceux qui ne le comprennent pas." _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
