如何在 Debian 启动时从 VirtualBox 挂载共享文件夹

Question

我知道已经有很多关于这个问题的问题，但是人们提出的所有解决方案都不适合我。我个人采取了这种/etc/fstab方法。这是文件内容的样子

david@debian:~$ sudo cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda1 during installation
UUID=e5de59a3-0619-47f9-9a08-858e1e4f6415 /               ext4    errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
UUID=b9140523-9685-48c4-a870-3604a8f58788 none            swap    sw              0       0
/dev/sr0        /media/cdrom0   udf,iso9660 user,noauto     0       0
GitHub-VM       /home/david/Documents   vboxsf  uid=david,gid=david,dmode=774,fmode=664     0   0

在哪里：

• GitHub-VM：是我从我的主机系统 (macOS) 共享的文件夹
• /home/david/Documents：是 VirtualMachine (Debian 8) 上的文件夹

当然，我没有忘记vboxsf在启动时强制加载内核模块。

david@debian:~$ sudo cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
vboxsf

遗憾的是，登录后，我的文档文件夹未映射到主机文件夹:(。我错过了什么？

挂载必须在vboxadd-service.service启动后进行。Systemd v220为此提供了特殊fstab选项，但除非您使用向后移植，否则对于 jessie 版本，您必须创建一个自定义安装单元。将以下内容放入/etc/systemd/system/home-david-Documents.mount：

[Unit]
Requires=vboxadd-service.service
After=vboxadd-service.service

[Mount]
What=GitHub-VM
Where=/home/david/Documents
Type=vboxsf

[Install]
WantedBy = multi-user.target

从 中删除相应的行fstab，systemctl enable home-david-Documents.mount然后重新启动。

检查您的启动日志，systemctl status home-david-Documents.mount看看它是否不起作用。
