This is the first image that built successfully and properly boots.
The only notable thing about it is that all submodules are build from scratch. Otherwise it should be identical to daisy (6.6). Would be nice if you boot it and load a config from production router to see if it loads and works properly.
Also I removed branding from the boot menu and improved the help text a little. Other references to Vyatta are still intact as they need a bit more work to remove. Just in case, it doesn’t mean the project is officially supported or endorsed by trademark owner.
