Estou substituindo meu roteador / AP de consumidor por uma caixa linux. Meu roteador consumidor discou para o meu provedor através de um link PPPoE em uma VLAN marcada. Eu tenho uma configuração de trabalho configurada em que ppp usa o dispositivo com tag enp7s0.201 e executa bem até que eu reinicie. Ao reinicializar, ppp aparece antes que o dispositivo de VLAN seja criado e morra imediatamente.

Eu removi um Before=network.target do arquivo [email protected] e adicionei um BindsTo=sys-subsystem-net-devices-enp7s0.201.device .
[me@router ~]$ sudo systemctl cat ppp@centurylink
[sudo] password for me:
# /usr/lib/systemd/system/[email protected]
[Unit]
Description=PPP link to %I
#Before=network.target
[Service]
ExecStart=/usr/sbin/pppd call %I nodetach nolog
[Install]
WantedBy=multi-user.target
# /etc/systemd/system/[email protected]/port-bind.conf
[Unit]
BindsTo=sys-subsystem-net-devices-enp7s0.201.device
No entanto, olhando para onde pppd é executado durante a inicialização, ainda é bem antes, quando enp7s0.201 está disponível.
EDIT: Sou um idiota. Esqueci que também precisava de um After=sys-subsystem-net-devices-enp7s0.201.device no drop-in.
