Never mind. I found the cure in the bottom of /etc/dhcpcd.conf, define a
static_eth0 and a fallback to it if a dhcpd server can't be found, did
it, rebooted and its fixed. I have a network. Why isn't that in the wiki?
Neither is there any reference to avahi that can be found in the wiki and
I spent around 2 hours search and browsing it.. Frustrating is an
inadequate description. Adequate isn't for mixed audiences.
Anyway, its fixed. How long? Beats me...
Cheers, Gene Heskett.
