"Making libc a kernel module"? Was that suggested somewhere? I don't even know what that means.

It was suggested in an earlier response to this article (by pj). But yeah, I don't know exactly what that would mean either.

Libc as a module ...

Concievably one could use a design similar to the VDSO "linuxgate" which was part of the Linux threads NG support a few years ago.

A default might simply implement the same mmap/linkage semantics that are in use already. However, any specific kernel image could over-ride that behavior.

I'm not advocating such an approach. I'm merely speculating on what someone might reasonably mean by saying such things.

Well that wasn't the suggestion, it the suggestion was basically make linuxgate.so into libc. (OR at least make libc work like linuxgate.so, probably making it relocatable, unlike linuxgate)
