The code conditionally sourcing zprofile moved to the generated .zshenv
zsh/zshenv was otherwise empty and is now one file less zsh has to open on
startup.
install needs to be re-run to update the generated .zshenv
Shipping the wanted symlinks didn't seem to work right and probably
isn't the right approach either. Instead, call into systemctl from
install.extra
May have to manually delete old wanted links and re-run install
