They typically don't export the serial console and don't have any other output devices. We perform the installation via SSH on such devices and start SSH automatically when the system boots so people can login. This works pretty well but sometimes a device stops to boot for no good reason. This is usually really hard to debug since we don't have any logs at all. I could activate netconsole in order to see kernel messages but then I still wouldn't see anything that's printed by the ramdisk and later when services are started. Ideally, I'd like to have an option for netconsole to show every message that is also shown on the console. Do you think that would be possible? -- Martin Michlmayr http://www.cyrius.com/
