Update ReadyNAS dropbox installation
Use su to become the user who is running dropbox and download/install the newest version.
su -s /bin/bash username
cd ~ && wget --no-check-certificate -O - "https://www.dropbox.com/download?plat=lnx.x86" | tar xzf -
Then you can check the daemon using
~/.dropbox-dist/dropboxd
Also, may need to upgrade the the DAEMON
environment variable in /etc/init.d/dropbox
