Virtualbox引導安裝不會卸載

Question

如果您在VirtualBox guest虛擬機上使用NetBeans，我在這里有一個非常有用的腳本。 似乎有一個問題：

如果您查看該腳本，它將寫入啟動腳本，該啟動腳本又將NetBeansProjects從主機系統裝載到Guest。 這很好。 但是，將創建一個附加腳本並將其移至用戶本地bin。 實際上，創建了兩個腳本：1）允許用戶安裝和2）卸載已安裝的文件夾以提供靈活性。

我測試了這些腳本，並且除了“ netbeans-unmount.sh”腳本以外，其他所有東西都可以在我的Ubuntu客戶機上運行。

它不會卸載在引導時已掛載的sirectory，我已嘗試授予腳本文件“ root”訪問權限...

關於這是否有效以及如何起作用的任何線索？ ：

#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

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

    echo "sudo /sbin/mount.vboxsf NetBeansProjects $HOME/NetBeansProjects" >> $tempWork/netbeans-mount.sh

更新：在終端中手動編碼卸載也無法卸載NetBeans Projects文件夾。 因此，我想我要問的是，如果系統初始化安裝了該文件夾，是否甚至可以卸載該文件夾？

Update2：仍然卡住，但是在etc/mtab查看后，我有了一些新信息。 這是我看到的：

...
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
...

很明顯，我必須多次運行sudo unmount〜/ NetBeansProjects！

諸如“ flat”之類的其他安裝選項也無法正常工作，因為它會卸載所有內容，而我只希望卸載目標目錄。

Answer 1

您可以通過以下方式卸載所有股票：

sudo umount -a -t vboxsf 

或使用fusermount -u

sudo fusermount -u /mnt

Answer 2

我重新檢查了所有的init文件，發現在/etc/init.d/rc.local添加了一些附加的掛載，現在我在測試這樣的字符串之前（例如）測試現有的字符串：

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

然后回顯“ JAVA_HOME = $ {javaUsrLib} /jdk1.7.0_01” | sudo tee -a / etc / environment fi
