从站被列为“可路由的”：
root@gentooserver /etc/systemd/network # networkctl
IDX LINK TYPE OPERATIONAL SETUP
1 lo loopback carrier unmanaged
2 eno1 ether routable configured
3 eno2 ether routable configured
4 bond0 bond no-carrier unmanaged
5 bond1 bond routable configured
5 links listed.
根据文档，它们应该被列为“被奴役”：https ://www.freedesktop.org/software/systemd/man/networkctl.html
最简单的解决方案似乎是添加
denyinterfaces eno*到 /etc/dhcpcd.conf。
