There is already a pull request to allow systemd-networkd to create
wireguard interfaces and configure wireguard-specific settings on them:
This will allow `*.netdev` files with `Kind=wireguard` to be created,
with all the wireguard-specific settings currently defined in
`/etc/wireguard/*.conf` and understood by plain `wg setconf`.
However, this PR will need to wait until wireguard is considered stable:
What currently already works in systemd-networkd is the whole
IP, Route etc. configuration, which is independent of the underlying
wireguard config and done in `*.network` files (man systemd.network).
wg-quick, which already brings systemd unit files, is too much, as it
also adds addresses and routes (in my case, it gets in my way, as I'd
like to set AllowedIPs to `::/0 and 0.0.0.0/0` but not default route),
but there may also be other cases where you don't need or want the whole
So as long as support for configuring the underlying wireguard netdev
interface entirely inside systemd-networkd is missing, I'd really favor
a unit file to only configure wireguard-specific parameters.

Right. This was simply copied from wg-quick at .service. ;-)
These two lines
could probably be replaced by
but I'm open to other suggestions :-)

Yes, this might make sense. Not sure if `wg setconf` will fail anyhow,
but failing before creating the interface might be a good idea, thanks :-)
