The problem seems to be in the stop() function in the /etc/rc.d/init.d/vboxadd. In the beginning of stop() it has if !umount -a -t vboxsf 2>/dev/null; then The absence of space between ! and umount seem to cause the problem because the shell interprets it incorrectly. Maybe it's a change in bash. When I added the space between ! and umount everything started to work." defect closed shared folders VirtualBox 2.2.0 fixed Linux Windows
