I started wiriting such a service but didn't finialized it yet. Tho, I wasn't sure if it needed to be implemented with wg-quick since upstream describe it as =C2=AB a very quick and dirty bash script for reading a few extra variables from wg(8)-style configuration files, and automatically configures the interface =C2=BB=C2=B9. > + > +(define-record-type* > + wireguard-peer make-wireguard-peer > + wireguard-peer? > + (name wireguard-peer-name) > + (endpoint wireguard-peer-endpoint > + (default #f)) ;string > + (public-key wireguard-peer-public-key) ;string > + (allowed-ips wireguard-peer-allowed-ips)) ;list of strings > + > +(define-record-type* > + wireguard-configuration make-wireguard-configuration > + wireguard-configuration? > + (wireguard wireguard-configuration-wireguard ; > + (default wireguard-tools)) > + (interface wireguard-configuration-interface ;string > + (default "wg0")) > + (address wireguard-configuration-address ;string > + (default "10.0.0.1/32")) > + (port wireguard-configuration-port ;integer > + (default 51820)) > + (public-key wireguard-configuration-public-key ;string > + (default "/etc/wireguard/public.key")) > + (private-key wireguard-configuration-private-key ;string > + (default "/etc/wireguard/private.key")) > + (peers wireguard-configuration-peers ;list of > + (default '()))) > + wg-quick(8) say that the =E2=80=9DAddress=E2=80=9D attribute can be specifi= ed multiple times and is =C2=AB a comma-separated list of IP (v4 or v6) addresses (optionally with CIDR masks) to be assigned to the interface. =C2=BB, so t= he =E2=80=9Caddress=E2=80=9D field should probably be =E2=80=9Caddresses=E2=80= =9D, a list of string. Some of the missing attributes from wg-quick(8) like =E2=80=9CDNS=E2=80=9D = or hooks seems realy usefull, maybe a =E2=80=9Cextra-config=E2=80=9D field to the re= cord could be added to support all of thoses attributes. Why having a =E2=80=9Cpublic-key=E2=80=9D field since it is derived from th= e private key? It seems to allow missconfiguration: what happen if the private and public part of a key don't match, or if only the =E2=80=9Cpublic-key=E2= =80=9D is set?

Can the provision's symbol be derived from the interface name to be able to do =E2=80=9Csudo herd stop wireguard-wg0= =E2=80=9D? > +(define wireguard-service-type > + (service-type > + (name 'wireguard) > + (extensions > + (list (service-extension shepherd-root-service-type > + wireguard-shepherd-service) > + (service-extension activation-service-type > + wireguard-activation))))) =C2=B9 https://git.zx2c4.com/wireguard-tools/tree/README.md#n47 Cheers, - Brice
