First question:
=================
Once a Kernel has booted can request the bios the different boot
devices and try to open them with a bios-disk driver or whatever the
name is?
Current problems:
====================
I do not know what's the live cd / non-live cd installer algorithm for
detecting which grub device corresponds to which linux device.
There's a man in hardwareguys.com which gets some strange results. He
installing Linux in his 4th drive and as long as it is detected as
/dev/sdg then the linux assign it: hd6 . :)

Probable solution:
=====================
If the answer for the first question is that NO here there is my
solution to problem.
We should make a command that iterates all the hard disks boot devices
and looks for the uuid from the hard disks. Once it has done so it saves
the result into a variable.
Then we can boot a kernel and pass this variable as a parametrer.
Example:
==========
grub> set
prefix=(cd)/boot/grub/
root=(cd)
grub> detectboot -s biosdevices
grub> set
root=(cd)
biosdevices=hd0|ffkei|hd1|ereok|hd2|er455
grub> linux /boot/knoppix-6.0-kernel root=/dev/ram
grubdevices=$biosdevices
grub> initrd /boot/knoppix-6.0-initrd
grub> boot
Then thanks to the "grubdevices=hd0|ffkei|hd1|ereok|hd2|er455" string
found in /proc/cmdline the knoppix boot scripts can check the uuid for
each detected hard disk and generate a valid devices.map file.
Any comments on this?
