I have one machine inmy lab that turns out to need to boot from /dev/sdq1

trust me, that partition info has LONG since scrolled off the screen by
the time it fails to mount and panics.

I ended up setting up a serial console to capture the boot to figure this
machine out, but that's a pretty extreme measure to have to go to.

P.S. I had to do this after grub failed to mount by label (my guess is
that grub only looks at so many drives before giving up on finding the
label) so don't tell me that I should just use labels and then I wouldn't
have to worry about this type of thing

There are two ways of constructing a software design. One way is to make it so simple that there are obviously no deficiencies. And the other way is to make it so complicated that there are no obvious deficiencies.
