--Sig_/GjjPT62J.LwN4AqkF9Kd14d Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable Hi hackers! While discussing my project's implementation details with my mentor, Alexander Leidinger, we've found that one of the ideas needs to be discusse= d with community, to find out possible use cases. That is, if it should be possible to spoof non-existing features. For example, if currently running kernel doesn't support FreeBSD 5.0 compat layer, "kern.features.compat_freebsd5" will be absent when querying=20 features list. The question is -- are there any cases when we want "kern.features.compat_freebsd5" be present? If some feature is not in kernel, then presenting its existence to the userland is useless and may be even harmful, if, for example, some application relies on this f= eature. Or there are some scenarios where such cheat is useful? --=20 Regards, Ilya Bakulin http://kibab.com xmpp://kibab612@jabber.ru --Sig_/GjjPT62J.LwN4AqkF9Kd14d Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (FreeBSD) iEYEARECAAYFAkwPTYcACgkQo9vlj1oadwinjACgqlgRxr7FxcbwfuSfauxLSANf mgsAoJhc97LJcb7TLQMb0oZY49xOVDn/ =ZWP2 -----END PGP SIGNATURE----- --Sig_/GjjPT62J.LwN4AqkF9Kd14d--
