WITHOUT_MODULES in /etc/make.conf doesn't work

I suppose modules save RAM by being loaded only when needed, but see the virtue of NO_MODULES=yes or MODULES_OVERRIDE in combination with putting everything needed in kernel config.

Building WITHOUT_USB would cause a severe loss of functionality, USB sticks, USB hard drives, even USB mice and keyboards wouldn't work.

I'll have to try that on my build/update of FreeBSD 9.0_STABLE i386 on USB stick.  Thanks for the hint!

This would be from the USB stick but with source base directory /STABLE1/usr/src (on hard drive).

I had already built FreeBSD 9.0_STABLE i386 on the USB stick from FreeBSD 9.0_STABLE amd64, and was successful booting that USB stick.

Sort of a dirty trick that you have to use usb/ulpt as opposed to ulpt, and a deficiency in the documentation.

Now is there any way to prevent ulpt.ko from loading when a USB printer is connected?
