Yes, indeed.  The IMAGE_FEATURES thing doesn't magically make the
postinsts work in offline mode, it just avoids any unconfigured packages
leaking into the generated image.  Fundamentally the recipes do need
fixing to either eliminate the postinsts altogether or, if that's not
feasible, make them work in offline root mode.

What sort of guidance are you looking for?  If there are particular
recipes with issues that you don't know how to solve, post them here and
we can discuss them.
