grub.conf
=========

Automate the build of grub.conf based on probe data. In this case, we take
the results from three probes, serial-console-speed, grub-serial-order,
and current-kernel to fill in a few variables.  In addition, we want
at least two entries set up for the kernel: a multiuser and a single
user option.
