Description

I'd like to be able to use "podman logs -f` and not print any existing log line. I want to follow only the new output.

It is not currently possible as podman logs -fl --tail 0 defaults to print all lines.

Should we change the type to Int64 and use -1 as default, or rather change the default to math.MaxUint64?

change the default to -1, so that we can change the semantic of
"--tail 0" to not print any existing log line.
