QUESTION 2
You have a 2.6.9 kernel on your system. You planned to recompile the kernel to add new features. You performed the following steps on the system:

1. Install the kernel source RPM.
2. Use the rpmbuild command to apply all patches (used in building the new kernel) in /usr/src/redhat/SPECS.
3. Edit the /usr/src/redhat/BUILD/kernel-2.6.9/linux-2.6.9/Makefile file to customize the new kernel name.
4. Navigate to the /usr/src/redhat/BUILD/kernel-2.6.9/linux-2.6.9/ directory and start with a kernel build configuration which is the same as what the currently running kernel is built with.
5. Use the mrproper command to clean up the tree and prepare it for the configuration and build process.
The remaining steps are given below:
6. The kernel image and selected kernel modules would be compiled with the make command.
7. Update the old configuration file so that the missing options now available in this kernel source tree are configured.
8. Copy arch/i386/boot/bzImage to /boot as the new kernel.
9. Build the initial ramdisk image.
10. Select options for kernel compilation–the various modules and options that can be configured when compiling a kernel.
