Hrm...you're root is mounted read-write, so the /etc directory should be
able to be updated by the tools.  Do you have /proc mounted at this point?
I'm assuming the SCSI driver is loaded at this point as well...Can't think
of anything else off the top of my head that would be wrong with that...

I'll see if I can reproduce on a system I have.
