[PATCH] fix unusual sysfs behavior for pcmcia_socket

[thirdparty/systemd.git] / klibc / klibc.spec

Summary: A minimal libc subset for use with initramfs.
Name: klibc
Version: 0.181
Release: 1
License: BSD/GPL
Group: Development/Libraries
URL: http://www.zytor.com/mailman/listinfo/klibc
Source: http://www.kernel.org/pub/linux/libs/klibc-%{version}.tar.gz
BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-buildroot
BuildRequires: kernel-source >= 2.6.0
Packager: H. Peter Anvin <hpa@zytor.com>
Prefix: /usr
Vendor: Starving Linux Artists

%description
%{name} is intended to be a minimalistic libc subset for use with
initramfs.  It is deliberately written for small size, minimal
entanglement, and portability, not speed.  It is definitely a work in
progress, and a lot of things are still missing.

%package kernheaders
Summary: Kernel headers used during the build of klibc.
Group: Development/Libraries

%description kernheaders
This package contains the set of kernel headers that were required to
build %{name} and the utilities that ship with it.  This may or may
not be a complete enough set to build other programs that link against
%{name}.  If in doubt, use real kernel headers instead.

%package utils
Summary: Small statically-linked utilities built with klibc.
Group: Utilities/System

%description utils

This package contains a collection of programs that are statically
linked against klibc.  These duplicate some of the functionality of a
regular Linux toolset, but are typically much smaller than their
full-function counterparts.  They are intended for inclusion in
initramfs images and embedded systems.
