It seems like the behavior would cause problems in the following workflow: - create first session (launch server) - detach - set environmental variables - create second session But I don't understand why you would want to follow this workflow in practice. When using tmux, all my work on that machine is done within tmux sessions, and I expect them to be sandboxed relative to each other. If I want to set an variable that's relevant to a session, I do it from within the session, not outside.
