I never saw a response for this, and while his message is archived, there
is no response archived.
I would like to know what the shell is for? Does anyone know? Lacking
that, can someone point me to a place I can find out?

During boot (2.4.18-k7) I see something about hit RET by 5 seconds for
shell. So I did and there's this shell that you can't do much more
than "set" in. After I typed exit the kernel couldn't find root and
I had to hit the reset button.
So what is this "shell" for? We are on the virtual disk phase still
here I suppose.
BTW, I notice that the first messages I see are tacked at the _bottom_
of the dmesg report.

I believe it is there as a debugging tool. It offers you a root-shell,
where you can modify the system in case it isn't booting correctly, i.e.
you can insert modules needed for booting (scsi, ext3, etc).
