Prefix `(nd)' in option-150 ...[Fwd: Option-150]

[Christoph Plattner]

Hello Mr. Okuji,

I have not analysed the contents of the documentation yet in this
detail, but is there mentioned, that the string passed over via
`option-150' (TAG 150) should include the `(nd)' prefix.

As described in the mail (see below), there are constellations,
where a missed `(nd)' can lead to a wrong behaviour (if root is
currently set to a local device and `bootp --with-configfile' is
called, for example.

In the beginning I thought, this was a bug. But this is really a
feature, as also a local installed config file (menu) can be
defined with "(hd0,0)/boot/grub/menu.lst" or similar.

So there should be a hint to that possibilities in the documentaion,
if there is not.

With friendly reards
Christoph Plattner
