[yocto] puzzle: simple recipe gets image dependencies

[Vladimir Molokov]

thank you for your answer!

when I comment out DEPENDS = "attr" line in "example" recipe
then there is no "bad-example" dependency:

"example" is just a simple recipe, it doesn't inherit image class
it doesn't even belong to any image, just standalone recipe.
I don't quite get the logic around initramfs
why does it add those dependencies to "example" recipe?
it doesn't if "attr" is commented out.
