[Voyage-linux] eth0 does not exist

[William M. Brack]

I did a little more research (that's a nice word for "Googling") on this,
and found that it's a known problem with udev on Etch (at least one bug
report is open).  Generally, it happens when you startup the system image
on one piece of hardware (at which time the file is created), and then
later reboot, either on a different piece of hardware, or with a
different hardware configuration (ethernet MAC address is changed).  For
Voyage applications, the easiest solution is to simply delete the file (a
new version will likely get created the next time the system is booted,
but the trouble should disappear).
