The documentation is pretty clear on how to setup file permissions. And as the user is already forced to edit all the config files, I don't think that is required to default to read only.   Here is an example of how I like to setup the FTP.   Step 1: Edit   # Mounts just media for read only # Directory Structure mkdir /tmp/FTP/ mkdir /tmp/FTP/Media mkdir /tmp/FTP/Media/Video mkdir /tmp/FTP/Media/Audio mkdir /tmp/FTP/Media/E-Book mount --bind /mnt/user/Media/Videos /
