## Current running kernel on Fedora ## KERN_DIR=/usr/src/kernels/`uname -r` ## Current running kernel on CentOS and Red Hat (RHEL) ## KERN_DIR=/usr/src/kernels/`uname -r`-`uname -m` ## Fedora example ## KERN_DIR=/usr/src/kernels/2.6.33.5-124.fc13.i686 ## CentOS and Red Hat (RHEL) example ## KERN_DIR=/usr/src/kernels/2.6.18-194.11.1.el5-x86_64 ## Export KERN_DIR ## export KERN_DIR
