This code is no worse than installing sysutils/ataidle - which also bypasses the driver. As it stands, FreeBSD out-of-the-box behaves in a way that adversely impacts laptop HDD life - and correcting this requires that the end-user both be aware of the problem and then find, install and configure a port to work around this. I am very uncomfortable with this and would prefer to see the base system require less user knowledge/intervention. --=20 Peter Jeremy --CdrF4e02JqNVZeln Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.10 (FreeBSD) iEYEARECAAYFAknLQtkACgkQ/opHv/APuIeKVgCfR28rM3fMkpKJ0OnXIOtr8Zpi eq4An0UwlhnHFRuof9KLA+FokxigwiYK =wYNo -----END PGP SIGNATURE----- --CdrF4e02JqNVZeln--
