Yes, this is the original image.

So far I haven't been able to because the IP 192.168.42.202 is not
showing up. It may be that DHCP is handing out another IP address the
MAC because I see 'pureos-test' showing up in my LAN. So far ssh has
been reluctant to let me in as 'purism' but I think I'll try again as
root when I see the MAC on my LAN again. 

Cheers,

Jeremiah
