Beats the heck out of me why grub-reboot goes through such convolutions.  It
invokes grub to actually rebuild the boot sector, when grub-set-default
will simply change which option is chosen automatically.

grub-reboot will _force_ that option to be chosen (no timeout) but
grub-set-default is much simpler.  After all, the only reason I'd usually
use it is because I have a bad tendency to forget to choose a new option
when the system restarts.

A little gui that would read menu.lst, give you the text names of all the
menu options and let you select one, would be nice.
