Re: Sharing ELF definitions between NetBSD userspace and kernel

Maybe it's just me being iconoclastic, but:

Why is this desirable?  There are numerous <sys/...> headers which
define/describe interfaces between userland and the kernel (which to at
least some extent ELF is); a simple example is <sys/socket.h>.

Admittedly, for ELF the situation is complicated by ELF being
externally defined.  But then, so, to at least some extent, are many of
the things defined/described by <sys/...> headers: <sys/socket.h>, for
example, describes APIs defined by history, and, ultimately, by a few
people at UCBerkeley.
