Re: Option-150

[Christoph Plattner]

It may be dependent of the TFTP-Server setup, but under normal
circumstances you must give the full path to DHCP, especially
for the files passed to GRUB (i.e. option-150).

So use

        option option-150 "(nd)/tftpboot/grubconfig"

The "(nd)" prefix is also important. There are constellations, where
this prefix is needed and this notation is the correct one, as you
can also define in `option-150', that GRUB should load a menu (config)
file installed locally, like:

        option option-150 "(hd0,1)/boot/configs/menu.lst"

If - for example - GRUB was booted locally (current root my be set
to `(hd0,1)'), and you use `bootp --with-configfile' to load a
menu from the server (passed by `option-150'), and if you have no
`(nd)' prefix in the `option-150', GRUB wants to load the file
from `(hd0,1)/tftpboot/grubconfig'. Therefore the `(nd)' is
important here !

With friendly regards
