right now `wg-quick@.service` uses the lines
ExecStart=/usr/bin/wg-quick up %i
ExecStop=/usr/bin/wg-quick down %i
ExecReload=/bin/bash -c 'exec /usr/bin/wg syncconf %i <(exec
/usr/bin/wg-quick strip %i)'
to interact with `wq-quick`.
The use of `%i` only allows the use of INTERFACE names, e.g.
systemctl up wg-quick@wg0
but prevents users of passing CONFIG_FILE paths, e.g.
systemctl up wg-qu...@-home-me-configs-wg0.conf
because `-home-me-configs-wg0.conf` does not get unescaped to
By replacing the first two lines with
ExecStart=/usr/bin/wg-quick up %I
ExecStop=/usr/bin/wg-quick down %I
would allow such usage.
The third line however is a bit tricky, as the argument to `wg syncconf`
is expected to be an INTERFACE name, and the argument to `wg-quick
strip` can also be a CONFIG_FILE path.
I am not sure how to solve the `ExecReload` argument issue, but I think
having the option to also pass in CONFIG_FILE paths to the unit would be
