我正在尝试使用 crontab 通过 sshfs 自动挂载目录。sshfs 命令：
/usr/local/bin/sshfs -o IdentityFile=/home/user/.ssh/id_ed25519.pub,idmap=user,allow_other,uid=1000,gid=1000 user@website:/home/public/ /home/user/website
使用 doas 运行时以及以 root 身份运行时均可行。但通过 cron 运行时，如下所示：
* * * * * df | grep website || /usr/local/bin/sshfs -o IdentityFile=/home/user/.ssh/id_ed25519.pub,idmap=user,allow_other,uid=1000,gid=1000 user@website:/home/public/ /home/user/website
cron 向邮件服务器发送电子邮件：

remote host has disconnected
知道我做错了什么吗？
干杯，Freddie xxx
