 I guess that will be the ways to go for now unless there are other
approaches.

Looking up execv it seems that it actually is a shorthand for execve, which
takes an additional char *const envp[]; which if I understand correctly,
will allow the explicit passing of environment variables instead of
inheriting.

Can subprocess optionally call execve?
