Interface's Address is not saved when SaveConfig = true in config

Interface's Address is not saved when SaveConfig = true in config

[ST]

Hello,

I have 
...
Address = 192.168.4.1/24
SaveConfig = true
in wg0.conf

1. if I add a peer with `wg set wg0 peer ...` WG doesn't add it
immediately to the wg0.conf file, only after I run `wg-quick down wg0`.
Why not? What happens if the system crashes unexpectedly?... The peer
will not be saved to the config file and the information will be lost.


2. once I run `wg-quick down wg0` I get:

Option "-all" is unknown, try "ip -help".
cat: /etc/resolvconf/run/interface/wg0: No such file or directory
[#] wg showconf wg0
sync: ignoring all arguments
[#] ip link delete dev wg0

Now the wg0.conf is enhanced with the peer details that was added
through command line, but the Address = 192.168.4.1/24 disappears from
the config. So running `wg-quick up wg0` again doesn't assigns IP to the
wg0 interface... What's wrong?

I'm using version:
apt list wireguard
wireguard/unstable,now 0.0.20180304-1 all [installed]

Thank you!

Out of date iproute2?

Which distro? Version?

Re: Interface's Address is not saved when SaveConfig = true in config

[ST]

Debian 8 Jessie
iproute2/oldstable,now 3.16.0-2 amd64

1. So is the iproute2 version out of date?

2. Is the issue with not saving new peers to the config file immediately as they are add but
rather only on `wg-quick down wg0` related to the version being out of date?

3. How are you going to implement SaveConfig = true once you add support for
/etc/wireguard/conf.d/[interface.conf | peers.conf]? How do you know to which file
should you save new peers?

Thank you!
