I was looking at why Linux says "can't find module st"
on the way up.
Turns out that the st.o (scsi tape) module is missing from
/lib/modules/2.2.5-15/scsi area so I copied it there.

Also, the /lib/modules/default link is not there because
of the bug in rc.sysinit so if you look for the
lines starting with:
       mtag=
and    mver=

It's trying to set up the 'default' link. But those 2 lines
need back-quotes ( ` ) after the equal sign and at the
end of the line to turn the resulting line into a string.
When I added that, I got the 'default' link and the error
on bringup didn't happen.

Funny think is that it still ran the scsi tape OK tho.
