How can I mount my Dropbox folder as the Documents folder on my encrypted home folder after startup?

http://askubuntu.com – What I am trying to do is bind: /home/username/Dropbox/Documents to /home/username/Documents on startup. On another computer running Ubuntu 12.04 I did this by placing the following line in /etc/fstab: /home/username/Dropbox/Documents /home/username/Documents auto bind However, on this computer, I have an encrypted home folder, so fstab claims that the location does not exist on boot, asking me to skip mounting it or manually repair. So my question is: how can I mount these folders only after I've logged into the user with the encrypted home folder? (HowTos)
