Originally the reason for making all the apps a SambaShare was because sometimes users needed access to edit or change something in the apps directory. This is not something TrueNAS does but we were trying to make it easier for normal people who wouldn't know how to get into those folders and edit a file if they needed. It's still something we discuss if it's still something we need to do or maybe we should just hide it since we're on our way to building a whole apps system.
