Virtualbox启动安装将不会卸载

如果您在VirtualBox guest上使用NetBeans，那么我认为这是一个非常有用的脚本。 似乎有一个问题：

如果您查看脚本，则会写入引导脚本，然后将NetBeansProjects从主机系统挂载到Guest。 这工作正常。 但是会创build一个附加的脚本并将其移动到用户本地文件夹中。 实际上，创build了两个脚本：1）允许用户安装和2）卸载安装的文件夹以提供灵活性。

我testing脚本和一切工作在我的Ubuntu客人，除了'netbeans-unmount.sh'脚本。

它不会卸载启动时安装的系统，我已经尝试给脚本文件“root”访问…

• 所有机器上的msi产品代码都是相同的
• 彻底删除并重新安装mysql
• 这可能知道在Ubuntu的设备安装和卸载时间？
• 停止MySQL数据库服务器：mysqld失败
• 你如何卸载* nix？

任何线索，如果这将工作，以及如何？ ：

更新：在terminal中手动编码卸载也无法卸载NetBeans项目文件夹。 所以我想我需要问，如果系统初始化挂载文件夹，甚至可以卸载此文件夹？

更新2：仍然卡住，但我有一些新的信息后，在etc/mtab查找。 以下是我所看到的：

 ... 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 NetBeansProjects /home/yucca/NetBeansProjects vboxsf rw 0 0 ... 

很明显，我必须运行sudo unmount〜/ NetBeansProjects多次！

额外的安装选项，如“平”，将无法正常工作，因为它卸载所有的东西，我只希望我的目标目录卸载。

 sudo umount -a -t vboxsf 

 sudo fusermount -u /mnt 

 if ! grep "JAVA_HOME=${javaUsrLib}/jdk1.7.0_01" /etc/environment
