Re: [CentOS] Very early PANIC during boot

On a vaguely related note, I also have pondered the following in the past; if you observe a system booting, you'll see all the "[OK]" and "[FAILED]" messages. Is there a log somewhere where you can check later on which services were started and which passed or failed?

the `dmesg` command will display the kernel message buffer, which includes messages prior to syslogd starting up. also look in /var/log/messages

as dmesg can eventually overflow with junk (iptables logging messages, for instance), I've been known to stuff a command like

dmesg > /var/log/dmesg.boot

into /etc/rc.d/rc.local just to keep a copy of the state of dmesg right after boot for later reference.
