Virtualbox引导挂载不会卸载

如果您在VirtualBox guest上使用NetBeans，我有我认为是非常有用的脚本。似乎有一个问题：Virtualbox引导挂载不会卸载

如果您查看脚本，它会写入引导脚本，然后将NetBeansProjects从主机系统挂载到Guest。这工作正常。但是会创建一个附加脚本并将其移至用户本地文件夹。实际上，创建了两个脚本：1）允许用户安装和2）卸载已安装的文件夹以提供灵活性。

我测试脚本和一切工作在我的Ubuntu客人，除'netbeans-unmount.sh'脚本。

它不会卸载这是安装在启动时sirectory和我试图让脚本文件“根”访问...

任何线索，这是否会工作，怎么样？：

#!/bin/bash 
#Author: Yucca Nel http://thejarbar.org 
#Will restart system 
PATH="/sbin:/usr/sbin:/bin:/usr/bin" 
export PATH 

#Modify these variables as needed... 
tempWork=/tmp/work 
startupScript=/etc/init.d/rc.local 
defaultNetBeansVersion=7.0.1 

echo "Provide NetBeans version (7.0.1 is default) then hit [Enter] :" 
    read NetBeansVersion 

    if [ -z "$NetBeansVersion" ] 
    then 
    $NetBeansVersion=$defaultNetBeansVersion 
    fi 

mkdir -p /$tempWork; 
cd /$tempWork; 

wget http://dlc.sun.com.edgesuite.net/netbeans/7.0.1/final/bundles/netbeans-$NetBeansVersion-ml-javase-linux.sh; 
sh $tempWork/*sh; 


#Add Netbeans launcher to your PATH. Doing so allows you to run 'netbeans' command from the terminal 
#This line will need to be changed if you changed the default install location (IOW Netbeans is not in ~/) 
sudo ln -f -s ~/netbeans-$NetBeansVersion/bin/netbeans /usr/bin/; 

#If you use VirtualBox , you can share your projects between Host and guest. Name of shared 
#folder must match 'NetBeansProjects' 
mkdir -p $HOME/NetBeansProjects 

if [ -f /sbin/mount.vboxsf ] 
then 
    sudo /sbin/umount /home/$HOME/NetBeansProjects 
    sudo /sbin/mount.vboxsf NetBeansProjects $HOME/NetBeansProjects 
fi 

if mountpoint -q ~/NetBeansProjects 
then 
#Add it to the universal start script to automate process... 
    sudo sed -ie '$d' $startupScript 
    echo "sudo /sbin/mount.vboxsf NetBeansProjects $HOME/NetBeansProjects"| sudo tee -a $startupScript 
    echo "exit 0"| sudo tee -a $startupScript 
    sudo chmod +x $startupScript 

#Create a mount and unmount script file and add it to users local bin 
    rm -rf $tempWork/* 
    echo '#!/bin/bash' > $tempWork/netbeans-mount.sh 
    echo '#!/bin/bash' > $tempWork/netbeans-umount.sh 
    echo '#!/bin/bash' > $tempWork/mount-from-host.sh 
    echo '#!/bin/bash' > $tempWork/unmount-from-host.sh 
    echo "sudo /sbin/mount.vboxsf NetBeansProjects $HOME/NetBeansProjects" >> $tempWork/netbeans-mount.sh 
    echo "sudo /sbin/mount.vboxsf NetBeansProjects $HOME/NetBeansProjects" >> $tempWork/mount-from-host.sh 
    echo "sudo umount $HOME/NetBeansProjects" >> $tempWork/netbeans-umount.sh 
    echo "sudo umount $HOME/NetBeansProjects" >> $tempWork/unmount-from-host.sh 
    echo "exit 0" >> $tempWork/unmount-from-host.sh 
    echo "exit 0" >> $tempWork/mount-from-host.sh 
    echo "exit 0" >> $tempWork/netbeans-mount.sh 
    echo "exit 0" >> $tempWork/netbeans-umount.sh 

    sudo chmod +x $tempWork/* 
    sudo mv -f $tempWork/*.sh /usr/local/bin 
    rm -rf $tempWork 
fi 

#This function is used to cleanly exit with an error code. 
function error_exit { 
    sleep 7 
    exit 1 
} 
#restart 
sudo reboot 
exit 0

更新：在终端手工编码卸载也没有卸载NetBeans的项目文件夹。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：仍然卡住了，但我看到etc/mtab后有一些新的信息。这里是我看到：

... 
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 
...

很显然，我必须执行sudo卸载〜/的NetBeansProjects很多次！

像'f-l-a-t'这样的附加挂载选项将无法正常工作，因为它会卸载所有内容，而我只希望卸载目标目录。

未能卸载通常是由于某些进程举行文件在该挂载点内的某处打开，或者将其用作其工作目录。文件系统不会允许卸载时仍然在使用（除非被迫）。 – 2012-01-13 15:21:19

@MarcB我刚刚添加了一些新的信息，你可以帮忙吗？ – thejartender 2012-01-13 19:48:29

我不知道它为什么会被多次挂载，但是您应该能够通过'fuser'命令找出哪些进程/用户在该挂载点上持有打开的文件。 – 2012-01-13 20:34:49

我重新检查我所有的初始化文件，发现有加入/etc/init.d/rc.local我现在测试写像在此之前现有的字符串一些额外的坐骑（为例）：

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

然后回声“JAVA_HOME = $ {javaUsrLib} /jdk1.7.0_01“|须藤发球-a的/ etc /环境网络

你可以卸载所有股：

sudo umount -a -t vboxsf

或使用fusermount -u

sudo fusermount -u /mnt
