Looks like it was introduced in FBSD7 somewhere. Looks reasonable to split parameters for /usr/src into a different file than /etc/make.conf thanks, Leon [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iEYEARECAAYFAku0fcwACgkQJCh4HSRvNnzncQCfaCmEt6zSyW+pk3yrYJ5Pgt3l nwkAniOf9dvnt3/1iWL6TUX/fwTawaWa =I8M0 -----END PGP SIGNATURE-----
