You ever want to see what your server is doing on boot up, but it's a remote server? You can log the boot messages to a file. I'm a little late to come across this, but it's still a mighty cool tip. First you need to emerge showconsole.
emerge -v showconsole
Next, we need to edit /etc/conf.d/rc and change this value to 'yes'.
On your next boot up, it will write to /var/log/boot.msg. Basically everything seen on console (except boot splash) will be written to this file. Very handy if you're having some boot issues.
