Yesterday I actually manage to get the imagebuilder for Edgerouter 4 to work😃.
Without making any setup changes I tried
Make image
And it went to work and then after a while finished without any visual warnings.
It produced the files it supposed to in the bin folder.
But the size and sha256 are not the same as the buildbot?
The buildbot system update file is about 11,5MB and my is almost 11,8MB.
I have tried to look at both manifest if something differ but it is not easy to manually spot any differences but the number of lines match.
How do I know it is safe to install this system update file the image builder produced?
