install kernel modules over network

Hi I'm a linux kernel newbie and I'm trying to figure out how to install kernel modules on to a test machine. I have built the kernel and copied it over to the test machine using and nfs mounted drive but when it comes to installing the kernel modules I can't find a way to get the 'modules_install' target to install to the network drive. I've been following 'Professional Linux Programming' and the author recommends passing in the INSTALL_MOD_PATH environment variable to make ,setting the appropriate path, but this does'nt seem to work for me. Some assistance would be well appreciated.

It did work. It just didn't do what you wanted. INSTALL_MOD_PATH needs to be to the root of the filesystem tree of your target system. Did you do this?

Code:

mkdir /tmp/foo
mount testmachine:/ /tmp/foo
make modules-install INSTALL_MOD_PATH=/tmp/foo
umount /tmp/foo
rmdir /tmp/foo
