我在 Fedora34 上使用自动挂载来实现在 Fedora15 上运行的 samba 共享。以下配置在旧的 Fedora27 中运行良好，但我必须添加forceuid并forcegid在 Fedora34 上工作。
$ cat /etc/auto.autofs
public -fstype=cifs,credentials=/home/stefan/.dixie_credentials,rw,nobrl,rsize=61568,uid=stefan,forceuid,gid=stefan,forcegid,file_mode=0660,dir_mode=0770,vers=1.0 ://dixie.tessier-ashpool/public/
$ tail -n 3 /etc/auto.master
+auto.master
/autofs /etc/auto.autofs
现在我的问题是：有时自动挂载会连续挂载该卷 5 次，并且在超时后仅卸载其中 1 次。我禁用了 autofs 服务并确保没有更多实例在运行。然后我手动运行自动挂载，这是输出（为了更好的可读性换行符）：

答案1
这表明鹦鹉螺就是罪魁祸首。当我有自动挂载的 /autofs/public 文件夹的书签时，nautilus 启动时会发生这种情况。没有书签它也能工作。
