Re: [meta-virtualization][PATCH 2/2] container-image-multiarch: add helper recipe

While I wait for my system level testing to complete, I'm going through the
pending patches.

This one brought a question to mind.

This seems oddly tightly coupled to the .inc in the other patch. What's the
value
of that list being in the .inc and then consuming it here (when there are
no other
consumers).

What would be the future consumers of the variable/list ?

If this was to be something overridable, shouldn't that be a ?= assignement
?
