如果您在VirtualBox的guest系统中使用NetBeans，下面这个脚本可能会很有用。但是似乎存在一个问题：
如果您查看该脚本，它会写入一个引导脚本，从而将Host系统上的NetBeansProjects挂载到Guest中。这个很好用。但是额外创建了一个脚本并移动到用户的local bin中。实际上，会创建两个脚本：1)允许用户挂载和2)卸载已挂载的文件夹以提高灵活性。
我测试了这些脚本，在我的Ubuntu guest中一切正常，除了'netbeans-unmount.sh'脚本。
它无法卸载在启动时挂载的目录，我尝试给脚本文件赋予'root'权限，但没有成功……
是否有关于如何使其正常工作的线索呢？

更新：在终端中手动编码卸载也无法卸载NetBeans项目文件夹。所以我想问一下，如果系统初始化挂载了该文件夹，是否可能卸载该文件夹？
更新2：仍然卡住了，但是在查看etc/mtab后我有了一些新信息。这是我看到的内容：
...
NetBeansProjects /home/yucca/NetBeansProjects vboxsf rw 0 0
NetBeansProjects /home/yucca/NetBeansProjects vboxsf rw 0 0
NetBeansProjects /home/yucca/NetBeansProjects vboxsf rw 0 0
NetBeansProjects /home/yucca/NetBeansProjects vboxsf rw 0 0
NetBeansProjects /home/yucca/NetBeansProjects vboxsf rw 0 0
NetBeansProjects /home/yucca/NetBeansProjects vboxsf rw 0 0
NetBeansProjects /home/yucca/NetBeansProjects vboxsf rw 0 0

NetBeansProjects /home/yucca/NetBeansProjects vboxsf rw 0 0
NetBeansProjects /home/yucca/NetBeansProjects vboxsf rw 0 0
...
很明显，我必须多次运行sudo unmount ~/NetBeansProjects!!
额外的挂载选项如“f-l-a-t”也不起作用，因为它会卸载所有内容，而我只想要卸载目标目录。
