I'll note that the applications for these super-tiny kernels are
places where it's not likely they would be using glibc at all; think
very tiny embedded systems. The userspace tends to be highly
restricted for the same space reasons why there is an effort to make
the kernel as small as possible.
In these places, they are using Linux already, but they're using a 2.2
or 2.4 kernel because 3.0 is just too damned big. So the goal is to
try to provide them an alternative which allows them to use a modern,
but stripped down kernel. If glibc or klibc isn't going to work
without splice, then it's not going to work on a pre 2.6 kernel
anyway, so things are no worse with these systems anyway.
After all, if we can get these systems to using a 3.x kernel w/o
splice, that's surely better than their using a 2.2 or 2.4 kernel w/o
the splice system, isn't it?
