This point (2) is in fact not correct, at least according to what I understood. My colleague Alexandre can confirm, but apparently, per-package staging has only been very recently introduced in OE. And yes, top-level parallel build was causing some spurious build failures. Alex, if you have more details, we're interested :) Thanks, Thomas -- Thomas Petazzoni, CTO, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
