The system already creates a copy of the first part of the system boot=20
output for you: /var/run/dmesg.boot -- this shows you what hardware the
kernel discovered as it probed all of the buses and so forth. It doesn't=
contain the rest of the output from all of the /etc/rc.d/* and
/usr/local/etc/rc.d/* startup scripts.
The simple way to capture all that is to enable console.log in /etc/syslo=
g.conf
-- you want to uncomment this line:
console.info /var/log/console.log
and make sure that /var/log/console.log exists, then restart syslog. Thi=
s
will log all console output, including the boot-up output.
Cheers,
Matthew
