Comment:
How did you manage to run that file with zsh? It's not `sv up wpa_supplicant`, not `/etc/sv/wpa_supplicant/run` (incorrect, btw), not `sh /etc/sv/wpa_supplicant/run` (incorrect, btw), not preceding any of that with `chsh -s /bin/zsh`, not even linking sh to zsh (incorrect, btw), all of that would still run with posix semantics.

Are you doing something like `source /etc/sv/wpa_supplicant/run` from zsh?
