Peter Anvin. It was developed mainly to be used during the Linux startup process, and it is part of the early user space, i.e. components used during kernel startup, but which do not run in kernel mode.[1] These components do not have access to the standard library (usually glibc) used by normal userspace programs. The development of klibc library was part of the 2002 effort to move some Linux initialization code out of the kernel.[2][3][4] According to its documentation, the klibc library is optimized for correctness and small size.[1] Because of its design, klibc is also technically suitable for embedded software in general, and even some full-featured programs such as the MirBSD Korn Shell. klibc is licensed under the full GPL license, which (unlike LGPL) imposes itself on any code linked with it. (This only applies to klibc as a whole due to embedding some Linux kernel derived files; most of the library source code is actually[5] available under a BSD licence from UCB or the Historical Permission Notice and Disclaimer.) This may limit its applicability to commercial embedded software.[6] During the Linux startup process, klibc is loaded from within a temporary RAM file system, initramfs. It is incorporated by default into initial RAM file systems that are created by the See also{{Portal|Free and open-source software}}
