Currently, the only thing that the kernel knows about environment
variables (or at least "most of the kernel," i'm not going to say that
i've looked in all of the machine-dependent nooks and crannies) is
There's this extra argument to execve() which specifies
a program's environment, and which should be plopped into
the newly-created address space.
It's not clear that changing that would be a real feature.
