How much detail do you want? You probably can't get a report on every
single process run during the boot process at all easily. However, you
can see the console output from the boot process.
To see what the kernel emits on boot-up, look at /var/run/dmesg.boot --
if you've got an old copy of dmesg.boot around somewhere, comparing the
two should show you any changes in the devices the kernel discovers when
it probes your system.
To see the output from the rc system, the best thing is to enable the
console log. Edit /etc/syslog.conf and uncomment the indicated line, as =
so:
# uncomment this to log all writes to /dev/console to /var/log/console.lo=
g
console.info /var/log/console.log
Then do:
touch /var/log/console.log
chmod 600 /var/log/console.log
/etc/rc.d/syslogd restart
Obviously, that won't help you see what happened on the previous reboot,
but on the next reboot you should see a transcript of the console output.=
Cheers,
Matthew
