我有一个外部 USB 硬盘。我想这样做：从启动时自动挂载它并通过 samba 共享它。
1）我把它放在fstab中，它在启动时正确自动安装，没有问题：
UUID=XXX /usb-hdd ext4 defaults,nofail 0 0
2）挂载后通过samba共享/usb-hdd。没问题。
[usb-hdd]
comment = raid5-usb
path = /usb-hdd
read only = No
valid users = michaelm
3）但是，如果机器重新启动，samba共享就会失败。可以很容易地解决
systemctl restart smbd
4）供您参考，“systemctl status smbd”在启动时返回以下消息：
May 06 14:44:37 storage systemd[1]: Starting Samba SMB Daemon...

我的猜测是，启动时，smbd 服务在安装 /usb-hdd 之前启动。如何纠正呢？
