[colug-432] DHCP (4) disappeared and a related question

[Rick Troth]

I should also mention that caching DNS seems to have quit about the same
time as IPv4 DHCP.

Thanks Rob.
That does lead to a hint ... what the web interface calls "IPv6 suffix"
gets entered to this file as the "hostid". So now I have an idea why the
thing has *always* ignored the IPv6 suffix I was so dutifully entering.
[sigh]

The daemon is running and serving IPv6 leases. (Just not nailed-down per
my intended suffix.) If I clean this up, it might resume leasing IPv4.
Or maybe it's tied to the DNS service issue? Still checking.

No doubt about that.
CeroWRT is/was solely to handle buffer bloat, so it never strayed too
far from the main trunk. And now it has been folded back in.

I think I already answered some of this for myself.
When I compared known OpenWRT URLs to what is coded in /etc/opkg.conf
*and actually drilled into the layout*, I saw one that appears to work.
Actually was able to install a test package.

Whahh??

Saw that at some point, and will try it when I'm ready to pull the "full
upgrade" trigger.

IT PROBABLY HELPS that I have a second 3800 as a spare. Need to recover
that from the office and maybe do the sysupgrade on it.

Cool!
