Description

From Fredrik Svensson on Slack:

I'm using multiarch/qemu-user-static to generate/run armhf images on an amd64 host.
So the original image has platform=linux/arm/v7 but the generated image gets platform=linux/amd64.
docker-slim works fine, the image is possible to run although docker complains the architecture is wrong
when running on the armhf device. Is there some way to set platform for the image as you can do
with docker build --platform=linux/arm/v7?

Research direction

No files or tests are named. Start by tracing how image metadata is handled during minification and compare the original and generated platform values, using the multiarch/qemu-user-static scenario described. Done means the generated image retains the original linux/arm/v7 platform instead of reporting linux/amd64.
