但是当我使用这些命令手动启动时wpa_supplicant，dhcpcd没有出现问题：
sudo ip link set wlp3s0 up wpa_passphrase tian `sudo cat /etc/netctl/wlp3s0-tian | grep Key | sed 's/=/ /' | awk '{print $2}'` | sudo wpa_supplicant -c /dev/stdin -D nl80211 -i wlp3s0 -B sudo dhcpcd -4 --waitip -L wlp3s0
如果 systemd 运行wpa_supplicant，它只需添加-P和-q。
所以，我想知道为什么 systemd 无法正确启动我的 wifi，而且每次都手动启动和重新启动我的 wifi 很无聊。
