networkdが起動時にeth0を起動しない

私はギガバイトbrixプロにDebian 8をインストールしましたが、ネットワークを除いてすべてが正しく動作しているようです。

systemd-networkd.serviceを有効にし、networking.serviceを無効にし、/etc/systemd/networkに適切なnetworkファイルを作成しました。ワイヤレスアダプターもwpasupplicantを構成して有効にしました。

システムが起動すると、wlan0.networkファイルが見つかり、インターフェースが起動し、リンクが検出されて完全に機能しますが、何らかの理由で、作成したeth0.networkファイルが表示されません（または記録されません）。リンクを検出せず、eth0をまったく立ち上げません。

システムが完全に起動した後、systemctl restart systemd-networkd.serviceまたはifup eth0を実行すると、インターフェイスが起動し、正常に機能する時点で適切に構成されます。起動時に起動しません。

これに対する解決策を見つけるために、他にどのような情報を提供する必要がありますか？

[〜＃〜]更新[〜＃〜]

次の行を/etc/network/interfacesに追加し、networking.serviceを有効にすると問題が修正され、すべてが起動時に表示されますが、古いinit.dシステムは使用しません。新しいsystemd-networkdを使用したいのですが、その環境でこれが発生している理由を知りたいのですが。

auto eth0
iface eth0 inet static
    address 192.168.1.10
    netmask 255.255.255.0
    gateway 192.168.1.1

[〜＃〜]編集[〜＃〜]

wpa_supplicant.serviceは、私がそれを無効にしたため欠落しており、networking.serviceは、現在機能している唯一のものであるため、有効になっています。

スタンザを/etc/networking/interfacesに追加すると問題が解決するのは、networking.serviceが有効になっているためです。 networking.serviceファイルを見ると、次のように表示されます（一部編集されています）。

[Unit]
SourcePath=/etc/init.d/networking
Description=LSB: Raise network interfaces.
.....
[Service]
.....
ExecStart=/etc/init.d/networking start
ExecStop=/etc/init.d/networking stop
ExecReload=/etc/init.d/networking reload

これは、これが避けたい古いSysVスクリプトとの互換性を提供するサービスであることを明確に示しています。

これはどこにも明確に記載されていませんが（私が見つけた可能性があります！）、SysVとの互換性はありませんが、まったく同じサービスを提供できるsystemd-networkd.serviceと競合すると思います。

したがって、私の推測では、networkingを無効にし、再起動してこれが（唯一の）ソリューションであることを確認します。

connman.serviceがsystemd-networkdに干渉しました

Connmanを無効にした後、bridgeとeth0が期待通りに起動しました。
