klibc (early userspace) in its current form is fundamentally a cleanup. 
  What it does is unload code from the kernel which has no fundamental 
reason to be kernel code (written during kernel rules, with all the 
problems it entails.)  The initial code to have removed is the 
root-mounting code, with all the various ugly mutations of that (ramdisk 
loading, NFS root, initrd...)

The original idea was due Al Viro; obviously, the implementation is 
mostly mine.

It is of course my hope that this will be used for more than just plain 
initialization code, but that in itself is a significant step, and one 
has to start somewhere.

Part of the reason it has taken as long is it has is just to try to make 
it as drop-in as at all possible.
