Description of problem:
The SUSE distributions have an additional make target called 'cloneconfig'.  This target creates a .config file that matches the currently running kernel.  All it does is copy /proc/config.gz to .config and then configure the kernel.  However, the real value of this is that all SUSE version ship with /proc/config.gz turned on by default.  This makes it trivial to rebuild the kernel with the same options as it was installed.

At our company, we have a driver that works with several different 2.4 and 2.6 kernels, and our number one problem is getting our customers to have a properly configured kernel so that they can build our driver.  Customers who have SUSE Linux are much easier to work with than users of other distros, mainly because of 'cloneconfig'.

cp /boot/config-`uname -r` .config
make oldconfig

The /proc stuff is not going to be enabled, as it serves no purpose other than
to waste memory for 99% of users.
