Yes, they does matter. Via setrlimit() you may not set limits
greater than kernel ones (like kern.maxfilesperproc,
kern.maxfiles under FreeBSD).

On the other hand, worker_rlimit_nofile usually required only when
you expanded kernel limits and want running nginx to expand it's
limits without restarting master (as rlimits usally defaults to
kernel limits at the time of process creation).
