Raspbian (Lite) 4.4 error on RPi 3 when trying to expand file system

[Ruffio]

On a fresh image of Raspbian 4.4, where I only added wlan0 info, I get this error when trying to expand filesystem:

pi@raspberrypi:~ $ sudo raspi-config --expand-rootfs

Be careful before using the write command.

The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).

Please reboot

Is that expected?
