Aha, now I remember. Consider things like the following, defined in poky.conf: DISTRO_FEATURES_append = " largefile opengl" This one, not so bad, I can easily override it. PREFERRED_VERSION_linux-yocto ?= "2.6.37+git%" PREFERRED_VERSION_linux-yocto_qemux86 ?= "3.0%" PREFERRED_VERSION_linux-yocto_qemux86-64 ?= "3.0%" PREFERRED_VERSION_linux-yocto_qemuarm ?= "3.0%" PREFERRED_VERSION_linux-yocto_qemumips ?= "3.0%" PREFERRED_VERSION_linux-yocto_qemuppc ?= "3.0%" All the above I could override.... but I'd rather be able to use the default without having to override them. This pollutes my distro config space unnecessarily in my opinion. DISTRO_EXTRA_RRECOMMENDS += "kernel-module-af-packet" Things like this are the kicker. I don't know of a way to remove just what poky.conf appended to a variable, and not wipe out the rest of the variable. -- Darren Hart Intel Open Source Technology Center Yocto Project - Linux Kernel _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
