Is there any way in FreeBSD to disable or enable devices on boot? NetBSD has a flag -c (userconf) to boot that does this, if it works. I tried it, but it immediately hung the computer, requiring Reset button. Man page can be viewed at http://netbsd.gw.com/cgi-bin/man-cgi?boot++NetBSD-current Section on userconf is -c Sets the RB_USERCONF flag in boothowto. This causes the kernel to enter the userconf(4) device configuration man- ager as soon as possible during the boot. userconf(4) allows devices to be enabled or disabled, and allows device locators (such as hardware addresses or bus num- bers) to be modified before the kernel attempts to attach the devices.
