[TriLUG] Updates installed, system won't boot now

[Jack Hill]

The root directive in the grub configuration should specify where your 
boot filesystem is (i.e. what should be the root when interpreting paths 
in the grub configuration for the kernel and perhaps ramdisk) Specifying 
the real root filesystem should be done in parameters passed to the 
kernel.

If it's grub2 (I think you said it was) I would suggest letting grub try 
to generate a new grub.cfg while you're in the livecd environment.
