I've a mounted iso image in the path:
/mnt/iso
Inside this iso I've an install script install.sh I run the installation script from the iso and at the end the script ask to the user if he want to umount the iso itself. If the user press "y" the script execute the following code:
cd /
umount /mnt/iso
echo "Installation completed!"
Unfortunately when the script tries to execute the umount there's an error
umount: /mnt/iso: device is busy
I suppose it's due to the fact that the virtual device is busy from the script itself. How can make it work? Tnx
