Hello Guix!

I am struggling to setup OpenVPN Service Type. Here is my current 
configuration.

*** START ***

(service openvpn-client-service-type
  (openvpn-client-configuration
   (remote
    (list
     (openvpn-remote-configuration
      (name "vpn.riseup.net")
      (port 1194))))
   (auth-user-pass "/etc/openvpn/Riseup.txt")
   (ca "/etc/openvpn/RiseupCA.pem")))

*** END ***

When I do, `sudo herd status vpn-client`, I get:

*** START ***

Status of vpn-client:
   It is stopped.
   It is enabled.
   Provides (vpn-client).
   Requires (networking).
   Conflicts with ().
   Will be respawned.

*** END ***

When I do, `openvpn /gnu/store/[...]-openvpn.conf`, I get:

*** START ***

Options error: --ca fails with '/etc/openvpn/ca.crt': No such file or 
directory (errno=2)

Could anyone please help me with this?

Regards,
RG.
