Why not but which package will provide the libGL.so file? in all case the u= sers might need to be able to switch the libGL.so file from the nvidia one to the mesa one, what would a user have to do for that, in particular a user using= only binary packages where a file can't belong to 2 different packages without conflicting? if someone have a better solution than a framework for that I'm open but no= the knob is not a solution for package people. regards, Bapt --0eh6TmSyL6TZE2Uz Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAk9F6PwACgkQ8kTtMUmk6Ewd/QCfXxbHBhX91uwFVWvIab/bZ0nP +qcAn3gzdWdRYeAmVR+N32WBALERK7fJ =gYLG -----END PGP SIGNATURE----- --0eh6TmSyL6TZE2Uz--
