commit 593dfac90938d62558de1fa13ac027c319284fe3

    image: per-device rootfs: first remove, then install packages
    
    Some DEVICE_PACKAGES definitions replace one package variant with another
    (e.g. wpad-mini is replaced with wpad). To avoid file conflicts, first
    remove, then install packages.
