Hi Damien,

I think I have a solution for you, where you can start 3 different vpn's 
with herd start vpn1-client, herd start vpn2-client etc.

Below is an ovpn-service.scm module, modeled after vpn.scm. which you 
can include with (use-modules (ovpn-service)) in your config.scm, by 
saving it in the same dir as config.scm. This is tested and works.

Now, I think you can modify all occurences of the word "ovpn", to, say 
vpn1, vpn2, and vpn3, and save 3 different files, and then use 
(use-modules (vpn1-service) (vpn2-service) (vpn3-service)) etc. in the 
config.scm. An example configuration in the config.scm OS-services 
section would be:

                  (ovpn-client-service
                   #:config
                   (let ([ base-dir 
"/home/myuser/src/my-guixsd-config/etc_openvpn/"]
                         )
                     (ovpn-client-configuration
                      ;; client
                      (dev 'tun)
                      ;; remote-random
                      (proto 'udp)
                      ;; mute-replay-warnings
                      ;; replay-window 256

                      ;; remote-cert-tls server lines is generated 
somehow
                      ;; remote-cert-tls server

                      ;; cipher aes-256-cbc
                      ;; ncp-ciphers AES-256-GCM:AES-256-CBC:AES-128-GCM
                      ;; pull
                      ;; nobind
                      (bind? #f)
                      ;; reneg-sec 432000
                      ;; resolv-retry infinite
                      (resolv-retry? #t)
                      ;; compress lzo
                      (comp-lzo? #t)
                      ;; verb 3
                      (verbosity 3)
                      ;; persist-key
                      (persist-key? #t)
                      ;; persist-tun
                      (persist-tun? #t)
                      ;; auth-user-pass /etc/openvpn/credentials
                      (auth-user-pass (string-append base-dir 
"credentials"))
                      ;; ca /etc/openvpn/ovpn-ca.crt
                      (ca (string-append base-dir "ovpn-ca.crt"))
                      ;; tls-auth /etc/openvpn/ovpn-tls.key 1
                      (tls-auth (string-append base-dir "ovpn-tls.key"))

                      ;; log /tmp/openvpn.log
                      ;; script-security 2
                      ;; resolv-conf scripts not needed for guix
                      ;; up /etc/openvpn/update-resolv-conf
                      ;; down /etc/openvpn/update-resolv-conf

                      (fast-io? #t)
                      (remote
                       (list
                        ;; Resolves to multiple vpn servers in location
                        (ovpn-remote-configuration
                         (name "whatever.ovpn.com")
                         (port 1196))
                        (ovpn-remote-configuration
                         (name "whatever.ovpn.com")
                         (port 1197))
                        (ovpn-remote-configuration
                         (name "whatever.ovpn.com")
                         (port 1196))
                        (ovpn-remote-configuration
                         (name "whatever.ovpn.com")
                         (port 1197))
                        )))))

Please let me know if this works for you!

Best regards,
David Larsson
