IBM RDAC: Installing the driver for a (not yet) running version

Well, kernel updates on our Linux servers running IBM’s RDAC driver (developed by LSI) is a real pest .. especially if you have to reboot the box two times in order to install the drivers/initrd correctly.

So I sat down and looked at the Makefile. Turns out, it just needs four tweaks in order to be working with a different kernel version (which you have to pass using environment variables to make).

After that, a simple make KERNEL_OBJ=/lib/modules/2.6.16.60-0.37_f594963d-smp/build OS_VER=2.6.16.60-0.37_f594963d-smp install correctly installs the modules in /lib/modules, rebuilds the correct modules dependencies and builds the correct initrd image.
