But, I found, quite by serendipity, in the raspios version of bullseye, a
fix. Look at the bottom of /etc/dhcpdcp.conf, if there is even a copy of
that on your system, this one now that I've looked, doesn't have it,
there is an example of what to do if no dhcpd is to be found locally.
static_eth0 can be defined, and below that, is an if no dhcpd to be
found, fallback to the static_eth0 definition.
Unpublished, not really mentioned in the man pages, but edit to put the
correct for your site data in it, reboot, and its working. So at least on
an rpi4 running bullseye, I found what looks to be the official way to
fix it. That file does NOT exist on an x86-64 debian bullseye install. As
to how you fix it on debian, I've not a clue.
I'd ask on the raspi forum, but I made the mistake of asking about a
realtime kernel a third time, way back in wheezy's time, which they
officially do not support, so my posting rights were turned off. I can
login, but can't post.
However, since this, on closer inspection, seems to be an raspios
problem, this is the last post on this subject.

There first has to be an activated server. And the only one here is
fielding the radio in the router when the radio is on, but its off to
keep the neighbors damned cell phone from using 300gigs a month on my
nickle.

Cheers Tomas, take care and stay well, Gene Heskett.
