Error received following "Quick Start for Adding a USB drive"

Greetings,

Received the following using the guide to install USB support, OpenWrt 17.0.4 on a WRT1900ACS router today -

link: https://openwrt.org/docs/user-guide/storage/usb-drives-quickstart

root@WRT1900ACS:~# service fstab start && service fstab enable
this file has been obsoleted. please call "/sbin/block mount" directly
root@WRT1900ACS:~#

--

Following the message, I went to the full USB install guide,

link: https://openwrt.org/docs/user-guide/storage/usb-drives

followed the instructions there for these topics:

[ Install and verify USB drivers ]
[ Verify that the OS recognizes the attached disk and partitions ]
[ Install file system drivers and create a file system in the partition ]
[ Automount the partition ]

and was able to view / access the mount point from within LuCi without issue.

FYI,
Regards, Rob
