%description
The kernel package contains the Linux kernel (vmlinuz), the core of your
Linux operating system.  The kernel handles the basic functions
of the operating system:  memory allocation, process allocation, device
input and output, etc.
This specific kernel contains grsecurity which is a collection of modifications to the Linux kernel targeted to increase security of your system.
