${PN} requires a kernel module to function properly. The recommended
approach is to install app-laptop/tp_smapi[hdaps], but the in-tree
module provided by CONFIG_SENSORS_HDAPS may work as well.

Common daemon parameters can be set in ${EROOT}etc/conf.d/${PN}. If the
package was installed with USE=libconfig, then the parameters can also
be set in ${EROOT}etc/${PN}.conf, although the former will take
precedence over the latter if both are used.

You can change the default sampling rate by modifing

  /sys/devices/platform/hdaps/sampling_rate

and you may need to enable shock protection manually by running

  # echo -1 > /sys/block/<disk>/device/unload_heads

as root.
