Let me make it CRYSTAL CLEAR. Jaunty booted up fine after the first 
installation. However, after updating the packages to whatever latest 
versions available, it apparently keeps messing up grub whenever it is 
shutdown or rebooted. I have done nothing at all with grub or grub2 
manually. I have not had a chance to check yet but I get the impression 
my problems stem from grub2 since I see comments and other stuff besides 
menu entries in the grub configuration file.

At this moment, it would seem that the LiveCD probably installs grub but 
the updates snuck in grub2. When I next get my hands on that box, I will 
verify what package(s) of grub are installed. Now if someone can tell me 
what script messes around with grub/grub2 during shutdown, I will 
happily file a bug report since I have no other Jaunty installation 
lying around.
