Time: 10:45am - 11:30am
This presentation examines the reasons why an administrator might want to compile their own kernel. The use of monolithic versus modular kernels for server systems is discussed and enhancements such as grsecurity that can be patched into the kernel are also featured. The pitfalls and drawbacks to compiling a custom kernel are also examined as these can play a central role in whether or not a system is supported by a vendor.
The presentation will feature tips for identifying hardware in a running system, the process for obtaining and compiling a kernel, and finally the installation of a custom kernel. Boot loaders and troubleshooting are also examined.
