If you set a variable in local.conf and that variable is not used because it is overridden by some other value, we can tell you, so we should. It could be presented like this: * In the build dashboard, we can add a list of the overridden variables * Clicking the variable name should probably show me the variable history in the 'BitBake variables' table Or something along those lines.
Toaster set conf values are always last, so I am closing this case.
