Description of problem: There could be running http server on / (something like python -m SimpleHTTPServer) providing easy access to all logs and other files during installation. This would be great improvement for debugging during installation. There is already inst.sshd which provides similar functionality but I believe that http is way easier and is worth it.
It should be possible to add a systemd target to initrd overlay. Not 100% user friendly, but already there.
We also already provide syslogging capabilities to log to a remote system, too. Honestly I don't want to add another mechanism, because that's just going to be another thing we'll have to debug and maintain. We've already got similar enough functionality.
