I support the addition of ssh, *even* with a weak random. The problem is, without ssh ... I would have to resort to telnet. I have to manage/operate/update our GNU/hurd through network and I am assuming many are in the same situation. "Weak" ssh is better than telnet. Having a minimal clothes is be

This prevents ssh & such to work with a simple apt-get, and that's wrong. If we cannot have strong security, than we tell it, but we do not suppress mostly-working programs just because of that. Anyway, a bad entropy generator isn't the main concern before using a GNU/Hurd box for s
