Thanks for the layers. I was able to pull together a thud build env
and do some tests.
For me, I see the defconfig being used as expected. The key words
there may be "as expected".
How were you determining that the defconfig wasn't being used ?
There are always some minor differences between most defconfigs and
what ends up the .config due to minor kernel version differences, or
the fact that by default, when a defconfig is fed through the
linux-yocto config process it assumes that the defconfig is fairly
complete and is intended to be a full specification .. as such, it
runs merge config with allnoconfig first, and then applies the
defconfig on top. So if something was perhaps being selected by an
option, or a default configuration was being assumed .. you will see
some minor deltas.
