beta bug? MACHINE_ESSENTIAL_EXTRA_RRECOMMENDS doesn't seem to work right...

I set MACHINE_ESSENTIAL_EXTRA_RRECOMMENDS += "bogus" in my local.conf.

This var is used in core-image-minimal; it's assigned to RRECOMMENDS_task-core-boot inside task-core-boot.bb.

Per the yocto glossary: "... the image will build if a file in this list is not found. "

But it doesn't build:

**********************

NOTE: Resolving any missing task queue dependencies
ERROR: Nothing RPROVIDES 'bogus' (but /opt/beta/yp-beta/meta/recipes-core/tasks/task-core-boot.bb RDEPENDS on or otherwise requires it)

************************

Seems like a bug?

Note, MACHINE_ESSENTIAL_EXTRA_RRECOMMENDS worked fine with a valid recipe.

No, this is not how the RRECOMMENDS mechanism works. There must be at least a possibility that the item in there exists (i.e., there must be a recipe that has it in its RPROVIDES, PACKAGES or an expression that would match it in PACKAGES_DYNAMIC). However, if a package corresponding to that item doesn't actually get produced, that is the situation that is ignored.
