Maxime,

I'm getting closer. I'm reading up on how the kernel treats networks, guile 
and guix. After I solve this issue I'll definitely do a write up to pass on  
the acquired knowledge, it'll be good for someone that is starting with guix, 
like myself.

That said, I have additional questions. First, in my wireguard configuration I 
need to call iptables. It was suggested to me that I should modify wireguard 
to accept iptables-service as a extension, and also modify iptables for it to 
be extended. Do you know any other way, or this looks like most appropriate?

Also, there are several wg0.conf generated at /gnu/store (because of many 
generations). How do I know which one is the most recent one, so I can check 
if my configuration is parsing correctly from guile? I tried a simple ls -lt 
but everything is showing Jan 1, 1970.

Thanks Maxime.
