"complete"? The only way to get everything that goes to the screen is
to connect up a serial port as a serial console and log it on another
box. bootlogd doesn't get everything. dmesg doesn't get everything,
and neither do the logs.
If you install the doc-linux-HOWTO package in whatever format, you'll
find the serial-console HOWTO. That and the other serial- related
howtos will allow you to connect a serial cable from the target box to a
logging box.
If you have a paralell printer, you can also have the printer act as a
console and print all messages. I don't know if it will work with a
USB printer.
