    finally have the time to work my way through the ELC 2013 hands on
kernel labs described here:

https://www.yoctoproject.org/tools-resources/presentations/working-kernel

since i'll almost certainly use some of them in my next yocto course,
so the occasional question for anyone who's already been down this
road.  start with lab 1.

    the doc mentions including the meta-yocto and meta-yocto-bsp layers
-- are those strictly necessary? the layer.conf definition file for
the lab1 layer doesn't list those layers as dependencies. what will
happen if i leave them out? what's the policy on explicitly listing
dependencies on those two layers in a new layer?

    also, just doing a basic fetch for lab1 produces:

ERROR: QA Issue:
/home/rpjday/yocto/k_lab/layers/meta-lab1-qemux86/recipes-kernel/linux/linux_3.0.18.bb:
Variable FILES is set as not being package specific, please fix this.

    is that deliberate? something that will be resolved later in the
lab as part of an exercise? just curious.

Probably not deliberate, the kernel labs aren't about packaging.
Which branch are you using for your tests ? Even if it's an old
release branch, there may have been some QA backports between the
time the lab was done, and the time you are running it.

   i'm using HEAD for everything, even though the labs dictate
poky-danny-8.0.1; if anything breaks because of that, i'll make a note
of it.

That's what I wondered. These were all done against 1.3, so the QA
warning (and other issues you'll see) are very likely caused by this
skew. For the next round of conferences, there are plans to update
them to use 1.4 and get required cleanup.
