Ok, I tried on the enigma list with no luck, so I'm going to try here.
Basic question is: Does anyone have any idea what I might be doing wrong
that I would get multiple duplicate default routes when I boot up? I have
to remove all but one of them by doing "route del -net 0.0.0.0" to get
things back to normal.
The message below provides a bit more detail on my
/etc/network-scripts/ifcfg-* files...
-t.
