So, externalsrc still doesn't touch the configuration, and it is not my plan to 
make it do so. However, users do need some way of setting up that configuration 
when checking out those sources for the first time, and if that's to be of any 
use to someone who just wants to make some minor changes, it should be the 
exact same configuration you get when you build the recipe as normal. That is 
what I believe "devtool modify" (at least with -x) should be doing, given that 
it is one means you can use to set up a development environment if you do not 
have one already.

We can certainly talk about the mechanism and work out the best way to do it, 
such that it fits in with how linux-yocto works and meets user expectations. My 
intent with this series was to get us to the point where we can at least 
experiment and have that discussion.

Cheers,
Paul
