UniFi setup wizard
Open web-interface https://server_adddress:8443 and provide correct country and timezone.
Additional notes
Go to UniFi Controller downloads for up-to-date firmware, software and documentation.
Additional notes
Default IP address on AP devices is 192.168.1.20.
Default username and password combination on AP devices is ubnt/ubnt or root/ubnt. Device authentication username and password is stored in settings->site->services on UniFi controller. You can copy it from there.
You can bootstrap initial configuration using /tmp/system.cfg configuration file, do not edit files inside /etc/sysinit/ directory.
# vi /tmp/system.cfg
Use cfgmtd utility to write modified file to flash.
BZ.v3.8.6# cfgmtd
Usage: cfgmtd [options]
-t <type> - Configuration type to use [1(active)|2(backup)]. (Default: 1(active))
-f <config file> - Configuration file to use. (Default: /tmp/system.cfg)
-p <persistent directory> - Directory to persistent dir. (Default: none)
-w - Write to flash action.
-r - Read from flash action.
-c - Clear flash action.
-o <mtd|file name> - Use mtd or file name. (Default: cfg)
-h - This message.
BZ.v3.8.6# cfgmtd -f /tmp/system.cfg -w

Use mca-cli to send adoption request from AP device.
$ ssh 172.16.0.21 -l ubnt BusyBox v1.11.2 (2017-07-12 21:44:37 PDT) built-in shell (ash) Enter 'help' for a list of built-in commands.

Adoption request sent to 'https://172.16.0.10:8080/inform'. 1. please adopt it on the controller 2. issue the set-inform command again 3. <inform_url> will be saved after device is successfully managed
UniFi# reboot
There is also /etc/persistent/ directory that can be used by various services.
BZ.v3.8.6# grep -r persistent /etc/* 2>/dev/null

There is also very interesting syswrapper.sh shell script located on UniFi AP devices with many useful actions.
BZ.v3.8.6# grep "^[a-z].*)$" /usr/bin/syswrapper.sh | sed 's/)$//'
