我有一个使用 Buildroot 构建的 Linux 嵌入式系统，它有 systemd v250。
在之前的builtroot 版本中，它使用的是systemd v232。
我定义了以下网络文件：
/etc/systemd/network/20-wired.network
[Match]
Name=usb0
[Network]
Address=192.168.89.14/24
此配置在我的旧 buildroot 映像上运行良好，启动后当我检查 IP 地址时：
# ip a
3: usb0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
link/ether 36:f9:b3:30:8f:b8 brd ff:ff:ff:ff:ff:ff
inet 192.168.90.14/24 brd 192.168.90.255 scope global usb0
valid_lft forever preferred_lft forever
但现在，使用更新的 buildroot，我无法在启动时分配 IP 地址：
# ip a
3: usb0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
link/ether 4a:1d:3c:df:39:ea brd ff:ff:ff:ff:ff:ff
当我尝试使用 networkctl 检查发生了什么时，我有以下输出：
● 3: usb0

我不太确定这里出了什么问题以及如何解决这个问题，有人有想法吗？
我预先感谢您的帮助。
问候，
