(New UI) Services/TFTP/Configure: Incorrect option name and defaults.
I'm testing the new UI with a FreeNAS system updated to the latest FreeNAS-11-Nightly Version.
I opened the configuration screen for the TFTP service and compared the options between new and old UIs. In the old UI, there is the "File Permission" field with all boxes in the "Read" row checked and the "Owner" column and "Write" row box checked. The new UI labels this option as "Umask" and has only the "Group" and "Other" column boxes check for the "Write" row.
