Is it at least telling you that the command is run?

Is this command run by FAI or are you doing it manually? However, here
(http://www.linuxsa.org.au/mailing-list/2003-07/1270.html) it states that you
need to install grub on all of your disks. In this case you will need to adapt
the scripts in the GRUB/ directory to fit your needs.
