BTW, I've tried the following packagegroup-base.bbappend to no avail:

python do_get_kernel_zimage_name() {
    new_dep = get_package_mapping('kernel-image-zimage', 'packagegroup-machine-base', d)
    d.appendVarFlag('do_package_write_ipk', 'vardeps', new_dep)
}
addtask get_kernel_zimage_name after do_package before do_package_write_ipk
do_get_kernel_zimage_name[depends] += "virtual/kernel:do_packagedata"


I suspect adding the varflag happens too late in this case, as the package
still isn't rebuilt on kernel updates.
