Thank you for replying.  I believe that this specific problem lies in
the way that I am (ad)using grubs 'device.map' file.  So, the bug is
probably invalid (and I'm happy for it to go away).

There is indeed a 'menu.lst' and a 'device.map' file in the=20
'grub config' (It is the entire contents of the /boot directory.)
and it get's copied to the target machine.

The previous version of GRUB (0.91-2) worked using the method I
described, which is why I logged the bug when this behaviour changed
(ie. something broke between this and 0.93+cvs20031021-8).

I will use the 'grub-install' script with the --recheck option
(maybe even deleting the 'device.map' file before using it).

[BACKBROUND: The installer was 'inherited' was a previous employee,=20
and the aim is to bring it as soon as posible into line with the
current Debian installer so that more sensible debugging/testing
can take place, and benefit everyone.]   =20

Cheers,
Paul
