I recommend to have a hard disk (or floppy) image which has GRUB on it that
uses tftpboot to get the files, including the menu(!) file.

This is the most convenient setup, as you don't need to ever change your
image.  The only drawback is the need of the tun module and thus root

I will check it in when I salvaged my Savannah account, ugh.

It can be useful to have serial output if you want to catch teh verbose
output of laden and wortel.  I suggest to have both variants around.  There
is a hidden possibility to get debug output from sigma0, I am not sure I
have the hack in the source, it involves a simple IPC.  It's not important
though.  In fact, having verbose outpout from any of the main L4 components
is not important.  The kdbg is useful though.  Just cause a $3 interrupt to
enter it from the source.
