When first using mender-convert in our products we realized that mender only supports booting compressed kernel images using uboot. So we issued a Pull Request:[https://github.com/mendersoftware/mender-convert/pull/97](https://github.com/mendersoftware/mender-convert/pull/97)

Unfortunately this change didn’t make it into mender-convert version 2. Currently I don’t see how this could be changed, as uboot related files seem to be downloaded from [https://d1b0l86ne08fsf.cloudfront.net](https://d1b0l86ne08fsf.cloudfront.net).

Where do these Files come from? How can I patch this behaviour?
