with update-alternatives removed from opkg-native I noticed that

virtual/update-alternatives-native defined in sane-feed-ipk.inc is not
installed at all before building any image, so created image is not
bootable, because there are missing links for busybox and kernel image etc.

where should be "DEPENDS = virtual/update-alternatives-native" to make sure,
that it is pulled before any package calls update-alternatives?

maybe tasks/task-boot.bb where is just virtual/kernel now?
