That=92s the idea.
You=92d have to also override board_default_buildkernel
and/or board_default_installkernel in like fashion if you
want to use a kernel.txz distribution. There=92s less=20
point in that on arm, though, since we don=92t yet have a
GENERIC kernel.
Caveat: Overriding board_default_installkernel is straightforward
for boards like RPi and BeagleBone if you=92re using the
U-Boot -> ubldr boot chain. Beyond that, it can get a little
weird.

I think Warner=92s concern was whether there was a way to
ensure that the (release) tarball and the (release) RPi
image had exactly the same bits.
Of course, the really time-consuming part of building a
release image with Crochet is when you add:
option UsrPorts
option UsrSrc
;-)
