Has this regressed at some point? Why was it not needed before?

This issue occurs when the rrecommends are not installed.

I wonder if it should be in the MACHINE_EXTRA_RRECOMMENDS in machine
configs, it will help a wide range of users who may be using
graphical images.

I hesitated to put it in MACHINE_EXTRA_RDEPENDS for Qemu targets.

Currently, kernel-modules are in MACHINE_EXTRA_RRECOMMENDS of Qemu
RISC-V and PPC64, which are not installed when NO_RECOMMENDATIONS="1"

Does core-image-weston have the same problem? If it does, then this
certainly needs to go to qemu include in conf/machine/

We don't control the kernel configuration to the point where we can
guarantee that something is built as a module or not.

Have you tried assembling the image with that option built-in, versus
a module ? Last I checked, a kernel-module* dependency won't be
provided by the built-ins, and this will trigger an error.

With that option appended, it isn't something that can be overridden
easily, and the qemu* + core images are used as a starting point for
demos, etc (whether or not that is a good idea is also debatable). If
a non-core kernel provider and qemu are used in a scenario like that
.. they can trigger the error.

Yes, the same issue occurs on core-image-weston, when
NO_RECOMMENDATIONS = "1".

So, instead of adding this rdepends in the sato image, I can add
kernel-module-virtio-input in MACHINE_EXTRA_RDEPENDS in
conf/machine/include/qemu.inc.

In addition, I'm looking to use a built-in virtio-input, as proposed by
	Bruce Ashfield.

Kind regards,
Thomas
