emerge --config =${CATEGORY}/${PF} or update-hddtemp.db (if USE
network-cron is enabled)

If your hard drive is not recognized by hddtemp, please consider
submitting your HDD info for inclusion into the Gentoo hddtemp
database by filing a bug at https://bugs.gentoo.org/

If hddtemp complains but finds your HDD temperature sensor, use the
--quiet option to suppress the warning.
