It certainly is not in /usr/src/linux (nautilus & terminal show that /usr/src is empty - yes, I am showing all hidden/system files), nor anywhere else I have looked. I have a default installation of RH 8.0, and through rhupdate, it has updated the kernel to 2.4.18-19.8.0 I am trying to install patch-o-matic 20030107, and the script prompts me for the KERNEL_DIR. This is extremely frustrating, and any help is hugely appreciated! <>< <>< <>< <>< <>< <>< <>< <>< <>< <>< <>< Timothy timothy@woodlandscenics.com
