We are not talking about an unrelated process, so forget about the
local environment of services: we are talking about a process
specifically fork+exec'ed from NTPD.

NTPD will set the stdout for the child process to point the right

On UNIX, it is natural to use a pipe(2).

On platforms without pipe(2) any other byte stream which can be
mapped onto stdout can be used: UNIX sockets, TCP connections etc.

This is really not complicated at all -- that's the entire point.

Never attribute to malice what can adequately be explained by incompetence.
