The container starts up OK and I am about to see if it is actually
doing what it is supposed to (I am just getting started with Coda
Protocol) but should I be concerned about those errors?

This usually occurs only once after a system reboot, when Podman was
not able to cleanly shut down containers. Most of the per-boot state
is kept on tmpfs filesystems and will be wiped without intervention on
reboot, but this is unfortunately not the case for IP address
reservations in CNI, which for reasons I've never heard adequately
explained live somewhere in /var and survive reboot. This error is the
result of us (unsuccessfully) attempting to clean these reservations.
In short, if it's only happening once per boot, the first time a
Podman command is run, I would not be terribly worried. You're
probably leaking one or two IP reservations per reboot, but the
default network for containers is a /16, so it's very unlikely this
will actually matter.
Podman 1.9.0 and higher replaced the code that did this (which not
very durable against failure) with a new method that is much more
reliable, so this should not be a problem in the future.
