[klibc] initramfs howto

[Daniel Thaler]

Heureka! An introduction that doesn't mention glibc at all:

Klibc is a means to this end: Userspace programs need a C library.
Klibc is a minimal C library, which contains the bare essentials needed for the
programs that will perform the userspace set-up in future, so that people can
keep their initramfs as small as possible.
The klibc distribution also contains a number of utilities that are
useful in an initramfs.

Better?
