I have a patch set which allows a port to install KLD source in a directory= =20 and have it picked up during a build/install kernel. This has a few=20 advantages over calling the ports tree from those makefiles. The prime one= =20 being that your source code does not change between upgrades without you=20 saying so. This is matters since (for example) the newer nvidia driver does= =20 not work on some hardware the old driver does (eg Fx5200 Go). It also means= =20 that the kernel build/install does not result in non kernel things being=20 altered. The disadvantage is that the KLD ports need to be modified to install the=20 source code in the right place (not hard) and that you will need to upgrade= =20 your ports tree to keep up with ABI changes if you update your source but=20 IMHO it's better to make this sort of action explicit - otherwise the end=20 user is in the position of not knowing what has changed on their system. Also speaking of KLD ports.. I really wish they wouldn't install=20 into /boot/modules (I patch so they don't) as it is a really good way to=20 shoot yourself in the foot during an upgrade :( =2D-=20 Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C --nextPart1142294.d4Tdyvpt0O Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) iD8DBQBCHpju5ZPcIHs/zowRAl0EAJ46ORi/H0f7cELLmBi0voPKiXGHDQCeL1FD x6Rat4Bi7CS8Dkw3xjt6i5o= =FtTs -----END PGP SIGNATURE----- --nextPart1142294.d4Tdyvpt0O--
