I just tried editing my /boot/loader.conf to make sure you haven't hit upon a bug. I added this line: ipfw_load="YES" and rebooted. The loader loaded both /boot/kernel/kernel and ipfw.ko as you'd expect. I then used the `unload' command and loaded only my kernel afterwards: OK unload OK load /boot/kernel/kernel OK boot -s Voila! Only my kernel and acpi.ko were loaded. Then, without editing my /boot/loader.conf I rebooted and inteerrupted the loader after ipfw.ko and the kernel were loaded. I disabled ACPI with: OK unset acpi_load OK boot -s Only the kernel and ipfw.ko were loaded. Then, I tried yet another way of disabling ipfw.ko at load time, and set ipfw_load to "NO" in my loader.conf. Only the kernel and acpi.ko were loaded. What is it that troubles you? I'm not sure I can reproduce it. - Giorgos To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
