The klibc is a minimalistic libc subset developed by H. Peter Anvin, intended to be used within an initramfs, as part of a multi-stage Linux boot process. It is incorporated by default into initial ram filesystems that are created by the mkinitramfs script in Debian and Ubuntu. Further more it has a set of small unix utilities that are useful in early userspace (cpio, dash, fstype, mkdir, mknod, mount, nfsmount, run-init, ..).

The klibc effort states as goal to move as much initialization code in Linux as possible out of the kernel^[1]: "some initialization is better done in user space" ^[2]
