Instead of asking whether I've read the thread, I'd appreciate if you could try to understand the point I'm making so we can make some progress. The gadget.yaml should represent accurately what goes into the image. Not one image in fact, but multiple, one per volume, and all of their partitions. We need to represent the "writable" partition in the gadget as well if it is supposed to be in those images, otherwise how do we provide parameters for it, and where does it go? Which position? And so on. A lonely "size" parameter is not meaningful in that context without further details. Then, how do we resize the boot partition, or any other one? <div class="gmail_extra"> <div class="gmail_quote">On Oct 12, 2016 2:56 PM, "Oliver Grawert" <<a href="mailto:ogra@ubuntu.com">ogra@ubuntu.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">hi, On Mi, 2016-10-12 at 14:14 -0300, Gustavo Niemeyer wrote: > It doesn't make much sense to have an option that controls the > generated disk image size by itself.
