How To Automount SSHFS Filesystems Automatically at Startup
There are two reasons why I did this. The first is that I constantly move files back and forth between systems using the command line, and SSHFS is the easiest way to do it. The second is that I am connecting my XBMC's together using MySQL for the database, but thumbnail files need to stay in the .xbmc/userdata folder on each machine. This will also setup an easy rsync without having to create an SSH connection on the fly.
