I think that the DATE specific part should be moved to separate recipe
which will clearly indicate it's just "build version".

I'm using shr-version recipe which just puts file in sysconfdir so it's
not so surprising to see shr-version recipe being rebuilt everyday and I
still know when the user last updated from feed.

It's also useful to pull such recipe into image by IMAGE_INSTALL not
through packagegroup (as otherwise the packagegroup could be rebuilt
every day as well - at least until runtime deps for packagegroups were
excluded in signature handler).
