writing boot/shutdown messages to file

["Vegard Lundby Rekaa" <vegardlr@student.matnat.uio.no>]

Hi all

while booting and shutdown I get some errormessages. I.e. while booting it
tells me something about modules not laoded correctly, but i have bo time
to read details.

Is there an option which writes boot and shutdown messages to a file?
