Hii @ashnamehrotra, In first look we want to extend user's control by giving them functionality for custom APT config file.
If you have something in your mind regarding this which can help me to solve this issue, please tell me. So we can work on this in proper way.

Hi @h4l0gen, based on the comment, I think we should set up the configuration within the original dm.config.ImageState prior to applying apt update on the resulting state based custom config input into Copa.
