When we do a build we get something like: opt/poky/1.0+snapshot/sysroots/powerpc-poky-linux Where does the 'powerpc-poky-linux' name come from? I think this needs to be more specific to the build if required because of how AVAILTUNES, etc are set. So something like: opt/poky/1.0+snapshot/sysroots/ppc603e-poky-linux - k
