> The launch script (nifi.sh) has a run argument that "supports" running in
> foreground. This could be useful with supervisors such as runit, however, the
> indirection provided by a subshell and an eval allow the instance to be
> detached from the session in certain circumstances and break trivial
> compatibility with runit.
> Adding an exec to RUN_NIFI_CMD before the sudo prefix, and removing the
> subshell invocation from the start argument else is a fix for my purposes.
> Something more considerate may be better. Additionally, if the feature should
> be desired in other similar launcher scripts, if there is an upstream source
> of that pattern I'm unaware of, it should be similarly modified.
