Well, it's definately the kernel source files that I'm looking for. However, I don't have a directory in /usr/src/ with the current kernel (2.4.21-0.13mdk.) I do have that directory in /lib/modules/ though. The only directories in /usr/src/ are alsa and RPM in RPM, there is BUILD, RPMS, SOURCES, SPECS and SRPMS.
Is there a command that will show the path to the current kernel source files?
