Would it be possible to expand this a bit? Like “replace VOLATILE_TMP_DIR by …” Regards, Jörg

Is there any variable I need to set in order for this new file to be found by BitBake? etc. Do we want to explain what the default means for the persistence of which directories? The same way it was done for VOLATILE_LOG_DIR/VOLATILE_TMP_DIR? Cheers, Quentin
