i have some problem
use Banana-pi m64
OS：BPI-M64 new image:2017-08-14-ubuntu-16.04-mate-desktop-beta-aarch64-bpi-m64-sd-emmc
how to set hostapd.service autorun at startup???
1. initial status
pi@bpi-iot-ros-ai:~$ sudo systemctl status hostapd.service
[sudo] password for pi:
● hostapd.service - LSB: Advanced IEEE 802.11 management daemon
Loaded: loaded (/etc/init.d/hostapd; bad; vendor preset: enabled)
Active: inactive (dead)
Docs: man:systemd-sysv-generator(8)
2. start hostapd.service , it's "Active:active (running)" , WIFI AP is connectable
pi@bpi-iot-ros-ai:~$ sudo systemctl start hostapd.service
pi@bpi-iot-ros-ai:~$ sudo systemctl status hostapd.service
● hostapd.service - LSB: Advanced IEEE 802.11 management daemon

Active: active (running) since Thu 2018-01-25 22:23:21 CST; 8s ago

Process: 984 ExecStart=/etc/init.d/hostapd start (code=exited, status=0/SUCCESS)

3. stop hostapd.service , use the command「sudo hostapd -B /etc/hostapd/hostapd.conf」, WIFI AP is connectable too
pi@bpi-iot-ros-ai:~$ sudo systemctl stop hostapd.service
pi@bpi-iot-ros-ai:~$ sudo hostapd -B /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
wlan0: interface state UNINITIALIZED->COUNTRY_UPDATE
4. set hostapd.serice to enable, and reboot
pi@bpi-iot-ros-ai:~$ sudo systemctl enable hostapd.service
hostapd.service is not a native service, redirecting to systemd-sysv-install
Executing /lib/systemd/systemd-sysv-install enable hostapd
insserv: warning: current start runlevel(s) (empty) of script `hostapd' overrides LSB defaults (2 3 4 5).
insserv: warning: current stop runlevel(s) (0 1 2 3 4 5 6) of script `hostapd' overrides LSB defaults (0 1 6).
pi@bpi-iot-ros-ai:~$ sudo reboot
Connection closing...Socket close.
Connection closed by foreign host.
Disconnected from remote host(bpi-iot-ros-ai.local) at 22:31:56.
5. After reboot...WIFI AP no signal , check hostapd.service status have fail
pi@bpi-iot-ros-ai:~$ sudo systemctl status hostapd.service

6. then restart hostapd.service, wifi ap can be connect
pi@bpi-iot-ros-ai:~$ sudo systemctl restart hostapd.service
pi@bpi-iot-ros-ai:~$ sudo systemctl status hostapd.service
