[GLLUG] Initrd issue

Hi All,

I know this is a long shot but I'm helping a colleague virtualise 
(Hyper-V) a RedHat 8 system. Yes I know - ssh, tls, and on an on are 
full of holes. But they have an application on the machine and well 
anyway......something about the 2.4 kernel and the version of gcc.... 
Its burried inside a lan and has no internet exposure. Anyway here's the 

I've done a test plain RH8 installation on Hyper-V and it runs fine, 
much to my surprise. So even if its not supported it seems to work, 
network and all.

Meanwhile on the P to V migrated system I've fixed up grub, grub.conf 
and fstab and rebuilt the initrd. I think its running the nash scripts 
in the initrd and I get the error:

Warning: Unable to open the initial console.

Earlier I was having a problem when running the RH8 rescue system. I 
found that the /dev/ filesystem needed manually mounted in 
/mnt/sysimage/dev before I did "chroot /mnt/sysimage". grub-install 
wouldn't work without the manual mount of /dev. I wonder if this is 
related. /dev/console is there when I run mkinitrd with /dev mounted 
manually. But there is probably something else in there I've missed. I 
removed the original cciss statement from modules.conf to stop it 
looking for the raid controller on the original host. I would have 
thought the a basic vga console module would be in there anyway but 
perhaps not...

Any clues???
