Why is this a SCSI ML problem? The problem is that the OS can't figure out
where to mount root from. Sounds like an OS problem.
I think the file system label is the leading candidate to solve this. One
really does not care if the root disk is called /dev/sda or /dev/fred. All
one cares is that you can boot your system and the right disks are mounted.
What I have seen so far with the fs label this either does solve this today or
it can solve this. I notice today on some systems the entries in /etc/fstab
already are "deviceless" in that it does not have the disk/partition but
simply the disk label.
Can lilo use a label for the root disk also? I have not looked into that yet.
If it does not can it? When I noticed the use of the label in /etc/fstab my
first thought was "alright, someone is solving this problem." I have not
taken the time - not a burning issue with me right now - to see if this is all
done yet though.
Keep in mind that the example where /dev/sda is where root lies is that "easy"
case. The hard case is what happens if someone installs on /dev/sdg. Now
they boot up with a disk array turned off. Is the mid-layer going to figure
out that what is now /dev/sda suppose to be /dev/sdg? Or they install to
/dev/sdb and /dev/sda goes bad so they pull it out?
