Yes, since otherwise the script would wait right there until the polling
daemon terminates (ie, forever).

Right. However, the only way for the polling daemon to use stdout would be =
to
not capture laptop_mode's output in the init script. You can't do both.
However, using a logger is the proper way anyway, since it would be weird (=
and
not all too useful) for a daemon to output to the console on which it happe=
ned
to be started (which could be no console at all, if it was started from an
ACPI event handler, for example!).
