我有一台运行 Ubuntu 22.04.1 LTS 的机器，并收到以下错误。我做了一些挖掘，在此过程中，UUID 似乎自行更新。每个分区的 UUID 都是唯一的。提前致谢！
该机器有2个硬盘-这是分区图：

来自 /var/log/syslog 的错误：
kernel: [ 698.762590] systemd-fstab-generator[3740]: Failed to create unit file /run/systemd/generator/tmp.mount, as it already exists. Duplicate entry in /etc/fstab?
systemd[3729]: /usr/lib/systemd/system-generators/systemd-fstab-generator failed with exit status 1.
答案1
您的系统可能已启用 systemd tmp.mount。检查以下命令：
systemctl status tmp.mount
如果是这样，您不需要/tmp在您的中安装/etc/fstab，因为systemd-fstab-generator将生成条目。
