在啟動時使用 systemd 掛載網路驅動器

我正在嘗試使用 systemd-service 呼叫的腳本在啟動時掛載我的本地 NAS。昨天我在 Debian 11-Install 上做了同樣的事情，它奏效了。今天在 Arch 上遇到了腳本執行時網路不可達的問題。這是服務：

[Unit]
Description=mount FRITZ.NAS network share
After=network-online.target
Wants=network-online.target

[Service]
Type=oneshot
ExecStart=/etc/systemd/system/connect_fritz_nas

[Install]
WantedBy=multi-user.target

這是執行腳本：

#!/bin/bash

### connecting to fritz nas
### cannot copy without "noserverino"-option

sudo mount -t cifs -o credentials=/home/user/.smbcredentials,vers=2.1,_netdev,noserverino,uid=1000,gid=1000 //192.168.178.1/FRITZ.NAS /home/user/networkshare

正如我在不同的文章和文章（arch wiki、freedesktop wiki）中閱讀的那樣，systemd-networkd.service需要啟用systemd-networkd-wait-online.service才能訪問network-online.target.

儘管如此，我在重新啟動系統後執行時收到此輸出systemctl status connect-fritz-nas.service ：

× connect-fritz-nas.service - mount FRITZ.NAS network share
    Loaded: loaded (/etc/systemd/system/connect-fritz-nas.service; enabled; vendor preset: disabled)

告訴我網路無法訪問。我知道我可以fstab用作替代方案，但在 fstab 上我遇到了同樣的問題。我監督了什麼還是我做錯了什麼？

我沒有使用由 systemd-unit 執行的掛載腳本，而是使用了 systemd.automount，您需要為其創建兩個文件（掛載單元）。Systemd.automount 使用一個自動掛載單元，它指的是一個掛載單元。兩個文件必須具有相同的名稱（副檔名除外）。一個叫home-user-networkshare.automount

[Unit]
Description=Automount networkshare

[Automount]
Where=/home/user/networkshare

[Install]
WantedBy=multi-user.target

另一個叫做home-user-networkshare.mount

[Unit]
Description=mounting the fritz nas
Wants=network-online.target
After=network-online.target

[Mount]
What=//192.168.178.1/FRITZ.NAS
Where=/home/share/networshare
Type=cifs
Options=credentials=/home/user/.smbcredentials,vers=2.1,noserverino,uid=1000,gid=1000

[Install]
WantedBy=multi-user.target

然後我同時啟用了systemctl enable home-user-networkshare.mount和systemctl enable home-user-networkshare.mount。下次重新啟動後，將安裝網路共享。有關更深入的資訊，請閱讀手冊。
