我是 Linux Mint 的长期用户。我刚刚在一台新建的台式电脑上安装了 Mint 21.1 Cinnamon 版本。
我已经设置了一个 systemd 挂载单元，以在启动时自动挂载 nfs 共享：
$ cat /etc/systemd/system/net-bungle.mount
[Unit]
Description=bungle fileserver
[Mount]
What=bungle:/srv/nfs4/pool2
Where=/net/bungle
Type=nfs
Options=_netdev,vers=4
TimeoutSec=10
[Install]
WantedBy=multi-user.target
$ cat /etc/systemd/system/net-bungle.automount
[Unit]
Description=automount /net/bungle
[Automount]
Where=/net/bungle
[Install]
WantedBy=multi-user.target
.mount 单元存在但未启用；.automount 单元已启用。
一切似乎运行良好：第一次访问目录时它会自动挂载，并且没有显示任何错误journalctl -u net-bungle.[auto]mount。
当我在 nfs 挂载（例如 nemo）中为目录添加书签时，就会出现问题/net/bungle/backup。输入登录密码后，桌面出现之前会有 15-20 秒的延迟（如果没有书签，桌面会立即出现）。
日志表明，nemo 在网络准备就绪之前在登录时尝试反复访问该目录，导致自动挂载失败：
journalctl -u net-bungle.automount

有人知道如何告诉 nemo 在启动时不要访问已加书签的目录吗？nemo --help没有显示任何有用的信息。

为将来遇到此问题的人回答我自己的问题......
问题出在 NetworkManager 与我的桥接以太网设置不兼容。我用 systemd-networkd 替换了 NetworkManager，问题就解决了。
