Only people who were using the FreeBSD-only ioctls need to change, simply by multiplying by 177 (the kernel was doing this conversion before). API is preserved although units have changed. In practice, I know of no applications (cdrecord, dagrab, tosha) written to the FreeBSD cdrio.h ioctls. However I can't check every port, hence the message. -Nate To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
