I am not planning to commit to anything here, just seeing what the 
general opinion is.

Okay, klibc takes 72KB, uClibc about 500KB (this is a copy built with 
their buildroot, including the ld, libcrypt, libdl and so on) and I 
think we can manually remove features we don't need. We will decrease 
the size for lvm, raid and cryptsetup users, and we could also dump udev 
and replace it with busybox's mdev I guess.

Some of the scripts would be easier to write as some of the standard 
tools are available (unlike with klibc).

We don't have to stick it in extra to play with it. I don't know about 
gcc spec files and such, maybe Jan can provide me with the links so I 
can look at this trick he mentioned.
