ok, I ran my tests and sad to say my memory seems to be correct. here's
what I did, and if you don't have the hardware you're just going to have
to take my word for it - btw, where are you located?
anyhow, here's what I did:
- patched the autoinstall script to exit right after /etc/mtab was
created and before systemconfigurator is called
- execute the command as per device_map in Grub.pm
grub --batch --device-map=/boot/grub/device.map < /dev/null > /dev/null
This resulted in:
Probing devices...
end_request: I/O error, dev fd0, sector 0
cat /boot/grub/device.map
(fd0) /dev/fd0
This is EXACTLY what I remember happening in the past.
As I said in an earlier email, grub 0.93 is not capable of recreating
the device map file if cciss devices are involved. Now for the second
part of all this, and I guess I need to reimage again to starte clealy
but thanks to SI, that's pretty easy to do...
If Grub.pm DOESN'T recreate the device map file, will the rest of this
work? I don't know, but now that I've gotten this far maybe I'll give
it a shot. But I have to run a few errands first...
