more BSP Guide pedantry involving customizing a recipe

[Robert P. J. Day]

  (you can tell i'm bored and want to get back up to speed on stuff
...)

  section 1.4 in BSP Guide, "Customizing a Recipe for a BSP", appears
to discuss a new layer, "meta-xyz", then suggests the new "interfaces"
file for this machine needs to go at the location:

meta-xyz/recipes-core/init-ifupdown/files/xyz/interfaces
                                          ^^^ ???

  but the files/ subdirectory of "xyz/" would appear to be necessary
(as we all know) only if this was a more general layer that
represented several machines (say, meta-ti) for which we *needed* to
distinguish between machines.

  so while the above might be technically correct, it might mislead
readers to think they *needed* to create a "xyz/" subdirectory for
that overriding interfaces file.

Actually, it *is* necessary if meta-xyz supports more than one
MACHINE and those targets have unique versions of the 'interfaces'
file (which is common since this file is being tailored for a
particular target machine)

n.b. in this case you'd have
    .../files/MACHINEa/interfaces
    .../files/MACHINEb/interfaces
and so on

  i realize that, but it's not clear from the wording of that section
that that could be a possibility. i just like to avoid potential
confusion, and giving the reader the wrong impression.

Hi, 

I have updated this section in the "latest" version of the BSP Guide.  Thanks for the input.
