Which uses a different kernel because GENERIC doesn't fit. The issue of including pcm by default is tough because FreeBSD is used mostly for servers, and they don't care about sound. On the other hand modern servers (certainly those that can run FreeBSD 5.x) don't care if the device is compiled in the kernel, because they can spare the +- 100k (gross estimate) of unused kernel memory. If you care enough, bring it up on -hackers, but expect a nice bikeshed to be built for you :) --Stijn --=20 I have great faith in fools -- self confidence my friends call it. -- Edgar Allan Poe --sm4nu43k4a2Rpi4c Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (FreeBSD) iD8DBQE/ZchVY3r/tLQmfWcRAkppAKCjarBd4sxDtttkir1QJfHjZagEJACfZgpu qYGIrATobyo99WjGjtUu7aE= =vlqe -----END PGP SIGNATURE----- --sm4nu43k4a2Rpi4c--
