.. warning::
The daemon is currently runs itself in the background using ``fork()``. On
architectures where ``fork()`` is not implemented, the daemon must be
"backgrounded" by using the trailing ``&`` in NSH at the moment. It is also
possible to us ``posix_spawn()`` from a parent program.
The daemon runs itself in the background using ``posix_spawn()`` due to
limitations with the NuttX implementation of ``fork()`` being architecture
dependent. This results in more consistent behaviour, but requires
``CONFIG_LIBC_EXECFUNCS`` to be enabled.
