I was hoping to get a little direction on my current situation. I am trying to use a model assertion along with the ubuntu-image snap to build a signed image for an amd64 device. Using the command “ubuntu-image snap example.model” I get the warning “WARNING: rootfs structure size 1.17 GiB smaller than actual rootfs contents 1.32 GiB”. Attempting to run the generated image results in an error similar to the warning above. After doing a little research, I think I need to modify the gadget snap I’m using to increase the system-seed/ubuntu-seed to 1400M. I used this guide and this gadget snap as my base. I was successful in compiling the gadget snap, but I am unable to figure out how to include it with my model assertion. Is there a command to generate a unsigned model assertion from the json representation and include the local compiled gadget snap?
