我编写了一个 systemd 服务，以便在机器启动时启动无线接入点。我的问题是，机器启动时它实际上并未启动，我似乎无法找出原因。手动启动服务效果很好。

我的wap.service系统单元文件：

[Unit]\nDescription=Enable the Wireless Access Point\nRequires=dnsmasq.service iptables.service NetworkManager.service\nBefore=dnsmasq.service\nAfter=iptables.service NetworkManager.service\n\n[Service]\nType=oneshot\nRemainAfterExit=true\nExecStart=/project/wap.sh\nTimeoutStartSec=0\n\n[Install]\nWantedBy=default.target\n\n

/project/wap.sh（大括号是 Ansible/Jinja2 变量替换）：

[Unit]\nDescription=Enable the Wireless Access Point\nRequires=dnsmasq.service iptables.service NetworkManager.service\nBefore=dnsmasq.service\nAfter=iptables.service NetworkManager.service\n\n[Service]\nType=oneshot\nRemainAfterExit=true\nExecStart=/project/wap.sh\nTimeoutStartSec=0\n\n[Install]\nWantedBy=default.target\n\n

相关/usr/lib/systemd/systemd --test --system --unit=default.target输出：

    -> Unit wap.service:\n        Description: Enable the Wireless Access Point\n        Instance: n/a\n        Unit Load State: loaded\n        Unit Active State: inactive\n        Inactive Exit Timestamp: n/a\n        Active Enter Timestamp: n/a\n        Active Exit Timestamp: n/a\n        Inactive Enter Timestamp: n/a\n        GC Check Good: no\n        Need Daemon Reload: …
