Why OBS call prepare step for every image type? https://github.com/openSUSE/obs-build/blob/4326a1ae347a8a9cd8abe57433f9beb2d... According to http://doc.opensuse.org/projects/kiwi/doc : "Successful completion of the prepare step is a the pre-requisite for the create step of the image build process. With the successful completion of the image preparation the unpacked root tree is considered complete and consistent. Creating the packed, or final image requires the execution of the create step. Multiple images can be created using the same unpacked root tree, for example it is possible to create a self installing OEM image and a virtual machine image from one unpacked root tree, under the condition that both image types are specified in the config.xml when the prepare step is executed. “
OBS can copy image tree if it worry about ‘images.sh’ differences between different image types.
there were times when building the image modified the tree. Maybe not kiwi itself, but some config.sh scripts or alike.
In any case it was needed to change in the way as it is today.
This could be because of images.sh that is called during create and needed for tree customizations for specified image type. I think OBS can just copy prepared once image tree to specified type and then call create (any COW on fs?) .-- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org
