I (and I suspect a lot of other folks) rather get rid of such autodetect and move it to userspace.

It doesn't really belong there. --3MwIy2ne0vdjdPXF Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) iD8DBQFAJ3j/xULwo51rQBIRAqNZAJ0aHEF7cuHAATseYUKfz2ie1Pc1pwCgojf/ f9AB6yE9A6qZgT16CSM3Bdw= =0Ztj -----END PGP SIGNATURE----- --3MwIy2ne0vdjdPXF--
