[yocto] couple questions about kernel dev manual, section 2

[Robert P. J. Day]

 some oddities in section 2.2.1 of the current kernel dev manual.
first, there's:

"The append file should initially contain the following text:

     FILESEXTRAPATHS := "${THISDIR}/${PN}"

  i was under the impression that the standard line would be:

     FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"

would it not? to make sure you can support potential layers on top of
layers, no?  if you absolutely *know* that won't happen, then, sure,
that will work, but i think the wording above is unnecessarily
restrictive.

  also, right underneath that, one reads:

"If you add any new files that modify the kernel recipe, you need to
place them in your layer in the following area:

     <your-layer>/recipes-kernel/linux/linux-yocto/"

IIRC, you *can* put them there but you don't *need* to. in fact, tom
zanussi's kernel labs place extra files simply under a "files/"
subdirectory (after setting FILESEXTRAPATHS to pick up that
directory). so, again, some wording that is unnecessarily strong and
somewhat misleading.

  thoughts?
