Hi Ludo, > I don’t think we should provide ‘syslinux’ in the installation image. > The image is already fat enough. Yep you're right, I added it without really understanding why it has necessary for the test to succeed. Now I understand why, it's because the image has no network access, so every package that will be needed further has to be specified. I add a packages list to "run-install" to solve this issue.
