[solved] systemd-resolved resolv.conf reverts to defaults

Hi all,

On my living room (HT)PC I have configured the network using systemd-networkd and I am using systemd-resolved to provide resolv.conf.
The .network file looks like this:

[Match]
Name=enp5s0

[Network]
DHCP=no
Address=192.168.23.200/24
Gateway=192.168.23.1
DNS=192.168.23.254
Domains=network23.local network24.local
IPv6AcceptRouterAdvertisements=false

[Route]
Destination=192.168.24.0/24
Gateway=192.168.23.254

Unfortunately, after an automatic login on the tty, resolv.conf is filled with the default values from resolved (Google's DNS servers). The rest of the network is configured correctly, including the defined route.
In this situation, networkctl status -a shows

● 1: lo
       Link File: /usr/lib/systemd/network/99-default.link
    Network File: n/a
            Type: loopback
           State: n/a (n/a)
             MTU: 65536
         Address: 127.0.0.1
                  ::1

● 2: enp5s0
       Link File: /usr/lib/systemd/network/99-default.link
    Network File: n/a
            Type: ether
           State: n/a (n/a)
            Path: pci-0000:05:00.0
          Driver: r8169
          Vendor: Realtek Semiconductor Co., Ltd.
           Model: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (Motherboard (one of many))
      HW Address: d0:50:99:39:03:db (ASRock Incorporation)
             MTU: 1500
         Address: 192.168.23.200
                  fe80::d250:99ff:fe39:3db
         Gateway: 192.168.23.1 (ASUSTek COMPUTER INC.)

To restore the correct settings, I can restart systemd-networkd. This gives me the correct settings in resolv.conf and it will show the correct "Network File" and "State" in networkctl status -a.
However, after a short while (~30 seconds) the problem comes back again.
On my laptop I am using NetworkManager without any issues, but I would prefer systemd-networkd on this system instead if it can be done without issues.

Re: [solved] systemd-resolved resolv.conf reverts to defaults

OK, since the config is static anyway, I ditched systemd-resolved and created resolv.conf myself.
