And that's why network-booted diskless clients and virtual guests have
all sort of useless modules loaded; the HW where the kernel package was
installed in this case is very different from the HW where the kernel
will run. If only there were a switch to prohibit ever looking at the
current machine's configuration when generating the initramfs...

I've tried a couple of times to use a Debian-built initramfs with a
custom built kernel. The kernel worked fine without an initramfs (it had
everything built in), but it did not boot with the initramfs.
