I take it that this "no" is only for the second part of the
assertion, and that you would subscribe to the shortend phrase
So it would at least be good that the internal use of it in musl
would be consistent.
If it is stated in POSIX that a userspace environ is a different
object from the one in the library, I am perfectly fine with
that. Documented behavior is a good thing, and userspace should see
its environ.
As it is currently, without my patch, execv would see __environ and
execvp would see the user space environ. I am still convinced that
this isn't desirable, both should see __environ, and that is what I
meant with my subphrase "and the C library would not see two distinct
objects".
