Thats *almost* correct. It builds an image from a *artifacts*.

My finding is: ...only if *artifacts* (also) includes a rootfs.

The image class dependency on rootfs seems very hardcoded. I cannot create a recipe that works without *creating* a rootfs.
(even though I have no rootfs other than the initramfs image which is already there, as an *artifact*).

inherit image

DEPENDS += "my-initramfs"


# This image does not generate its own root filesystem
# I have tried to exclude it, but it's hardcoded even in buildhistory.
#do_rootfs[noexec] = "1"
#do_image[noexec] = "1"
#do_image_wic[noexec] = "1"
#do_rootfs_wicenv[noexec] = "1"
