FTP-based Provisioning

The Automatic Update feature provides limited support for FTP/FTPS connectivity. Periodic polling for updates is not possible since these protocols do not support conditional fetching (i.e., updating files only if they are changed on the server).

The only difference between FTP-based provisioning and those described in HTTP-based Provisioning and Provisioning from HTTP Server using DHCP Option 67 is that the protocol in the URL is "ftp" (instead of "http").
