Is there a way to customize the Codespace VM image or packages? I need Docker Engine 25 or later. If there's no way to customize the VM image, when's the next Docker Engine upgrade? The last upgrade from 23 to 24 was Jan 2024.

Right now I see the below.

Thanks. This didn't work for me. I tried with this repo and got this error.

Error: Command failed: docker buildx build --load --build-context dev_containers_feature_content_source=/tmp/devcontainercli-root/container-features/0.80.0-1759164256547 --build-arg _DEV_CONTAINERS_BASE_IMAGE=mcr.microsoft.com/devcontainers/universal:3 --build-arg _DEV_CONTAINERS_IMAGE_USER=root --build-arg _DEV_CONTAINERS_FEATURE_CONTENT_SOURCE=dev_container_feature_content_temp --target dev_containers_target_stage -f /tmp/devcontainercli-root/container-features/0.80.0-1759164256547/Dockerfile.extended -t vsc-codespace-test-27b31c20aa9ae51d6f9c90d616e43fd31f089c4b7e69a126e831d14a2153cfc7-features /var/lib/docker/codespacemount/.persistedshare/empty-folder

Do you have a working example? Are you sure this is possible?
