Specify directory with spaces in /etc/fstab
If you want to add a filesystem to mount in /etc/fstab you need to use the octal ASCII value which is \040. In my case I have created a separate filesystem for VMware virtual machines:
/dev/mapper/vmwarefs /var/lib/vmware/Virtual\040Machines ext3 defaults 1 1
If you have any other special characters which are causing problems you can check with
man ascii
for the value you need to specify.
