Failed to open "/ on". Specified location is not supported.
I configured eth0 according to the manual instructions for a static IP in /etc/network/interfaces on the Debian Wiki. I can use the terminal (stterm) to ping other computers on the network. I can SSH to other computers. I can apt-get update. I can surf the web (I'm posting from the affected machine). I have Samba installed.
Near as I can tell addressing the network, and seeing the windows devices should be fine.
