> There are times between designign a MiNiFi flow that the initial file to be
> Tailed is not know at design time. Often the design and deploy may be
> seperates by days and thus non-deterministic. Therefore, the initial file
> name is not known ahead of time. This could be fixed by modifying the
> config.yml on the agent box when it is deployed, however, that seems to be a
> more brittle solution and puts the burden on the person doing the agent
> deploy. This model may also not work when the MiNiFi management facilities
> are realized.
