Hi,

Should it be possible to set PREFERRED_VERSION in the image definition
files?
Conceptually, no. An image recipe is a recipe. Global data is global and
local data is local. A recipe (image or package) set local data only.

I have 2 image files:
- image1.bb
- image2.bb : PREFERRED_VERSION_package_1.0.0

I have a package with 2 versions:
- package_1.0.0.bb
- package_1.1.0.bb
Correct way is different distro or machine. Obviously the build impact
is high for such as small difference in images.

Two possible hacks to me:
1. package10_1.0.0.bb and package11_1.1.0.bb but then you need to manage
the dependencies inside recipes (those (r)depending on package10 or
package11). If it's a "final" package which isn't a dependency of
anything else except the image, that's actually not too bad. Then in the
image you add package10 or package11.

2. Have an intermediate recipe which RDEPENDS_${PN} += "package
(=1.1.0)" and the other on "package (=1.0.0)" and install this
intermediate recipe in the appropriate image.

There are shortcomings in both hacks (otherwise they wouldn't be called
that way :) ).
