Since our current policy dictates that we use the same kernel in the
install process, as in the fully installed system, we must have both
IDE and SCSI compiled in. Otherwise we must ALL boot with some form
of initrd mechanism, and I don't know about you, but I'm not sure I

Pardon? 'No IDE/SCSI, but initrd w/ IDE'? Or did you mean ether one of them?

I didn't like ether one of you ideas, because it will make things more
difficult for people to change kernel... changing initrd image etc, etc...
But I agree, that it scales better than a lot of floppy images tough.
As I said earlier, one HUGE kernel (not good, but it will surely support
most hardware) on the first (and optionally only) floppy, the rest (root,
modules etc) on 'fetch-able media' (CDROM, FTP, TFTP, NFS etc) would be
better... Not good, but better than having to ALWAYS boot up via a initrd
One good thing about you way, though is that in theory, you can just remake
your SCSI card's module, and copy that to the initrd image, and off you go...
Hmmm... I think I'm going to at least try out this way, to see how much (memory/speed)
I would gain from it... Unfortunately I don't have a monitor to my PC (going
through a HP via ssh), so I can't see much of the booting... :)
We are GNU. You will be GPL'ed. Resistance is futile.
