Kernel will build with both these options, but will it make things go awry? Is ATA_CAM deprecated? As far as I can see, ATA_CAM isn't currently documented.

The usual way is to have a separate config file for each, although you can come up with other ways if you feel like being clever. The config files support an include functionality, so working through the files is pretty easy. As for leaving out modules, there are a number of options documented for make.conf(5) and src.conf(5) that give you various kinds of control. > In Linux, beginning with kernels 2.6.*, cdrtools work without the ATA-SCSI dance. You don't say what version of FreeBSD you're on. I'm still using RELENG_8, so I may be missing some choices for later versions, where I understand that the CAM code has been significantly reworked.
