How to make read-only 'virtual' exFAT directories for FTP users on Synology NAS running DSM 6

Update, December 2019: installing third-party scripts or package managers which run on boot may overwrite the file /etc/rc.local which I initially recommended using. I've revised this article to recommend a better autostart script directory; feel free to borrow the simple start/stop script I included at the end of this post.
