I have what I think is a very useful script here if you use NetBeans on VirtualBox guest. There seems to be one problem:

如果你看看这封信件,就会把网上贝曼项目从东道国系统排到客座。 罚款。 然而,另外还制作了一个文字,并将其转移到当地用户的双版上。 事实上,有两种文字: (1) 允许用户站立起来,2) 放弃安装的夹,以允许灵活性。

我测试了我的乌班特客的文字和一切作品,但网本是一纸。

它将不 un在boot子上安装的轨迹,而我已尝试让文字材料扎根。

Any clues as to if this will work and how? :

Update: Hand coded unmounting in terminal also fails to unmount the NetBeans Projects folder. So I guess I need to ask if it s even possible to unmount this folder if the system initialization mounted the folder?

Update2:Still Stuck, but I have some new info after looking in etc/mtab. Here is what I see:

...
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,我不得不多次起诉“~”项目!

Additional mount options like f-l-a-t won t work either as it unmounts everything and I only want my targeted directory unmounted.
