%description core
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.

%description modules
This package provides kernel modules for the core kernel package.

Summary: Header files for the Linux kernel for use by glibc

Obsoletes: kernel-headers < %{kverstr}, glibc-kernheaders < 3.0-46
%description headers
Kernel-headers includes the C header files that specify the interface
between the Linux kernel and userspace libraries and programs.  The
header files define structures and constants that are needed for
building most standard programs and are also needed for rebuilding the
glibc package.
