Thanks, I'll have to document that. In .config, I think you need
"CONFIG_HOTPLUG=y". I don't know if the kernel can even be built
without it. What output do you get from the command
cat /proc/sys/kernel/hotplug
I get...
/sbin/mdev
That's what you need. *IF THAT IS NOT THE CASE FOR YOU* the docs at
http://git.busybox.net/busybox/plain/docs/mdev.txt give 2 options...
1) If you have a proc file system (yes we do), the way to do it is
echo /sbin/mdev > /proc/sys/kernel/hotplug
2) For embedded systems without a proc filesystem, you can
sysctl -w kernel.hotplug=/sbin/mdev
Option 2 would probably also work for Gentoo, but the proc filesystem
makes things a lot easier.
In my case hotplug support was enabled and /sbin/mdev was already
listed in /proc/sys/kernel/hotplug. Google turns up a lot of
documentation for mdev on stripped down embedded systems. Trying to
apply it to a desktop PC is breaking new ground.
