Falta el directorio / etc / en homebrew

Actualmente estoy trabajando en la configuración de un servidor IKEv2 VPN con strongswan. Estoy trabajando en una Mac con v10.11.16 (El Capitan). He estado haciendo referencia al siguiente tutorial: https://www.digitalocean.com/community/tutorials/how-to-set-up-an-ikev2-vpn-server-with-strongswan-on-ubuntu-16-04

Me he encontrado con problemas con el Paso 4 del tutorial. Parece que cuando instalo strongswan usando homebrew, los archivos de configuración no terminan en mi carpeta etc /, como se supone que deben hacer. De hecho, parece que no puedo ubicarlos en ningún lugar de mi máquina. Cuando busco en mi directorio / usr / local / opt, no hay ningún directorio incluido. Parece que mis archivos de configuración para strongswan son AWOL. ¿Alguna idea de dónde podría ponerlos?

Si ha instalado brew y strongswan en las ubicaciones predeterminadas, la ubicación estándar de "brew", etc. es / usr / local / etc /.

La carpeta contiene todas las carpetas y subcarpetas requeridas por strongswan / ipsec, etc.

Entrar ls -Ral /usr/local/etcdebería revelar algo como (ligeramente redactado por mí para omitir mi nombre de usuario y algunas carpetas no relacionadas se eliminaron de la salida):
