klibc-utils | small statically-linked utilities built with klibc | Mehr ...
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.
libklibc | minimal libc subset for use with initramfs | Mehr ...
klibc 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.
libklibc-dev | kernel headers used during the build of klibc | Mehr ...
This package contains the set of kernel headers that were required to build klibc and the utilities that ship with it. This may or may not be a complete enough set to build other programs that link against klibc. If in doubt, use real kernel headers instead.
