The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc. This variant of the kernel has numerous debugging options enabled. It should only be installed when trying to gather additional information on kernel bugs, as some of these options impact performance noticably.
