I recently bought a RPI Zero W.
I've installed OE/LE on many arm boxes before. They have always had full-sized USB ports, so I've always done the initial config using a USB keyboard.
The RPI Zero W has only micro USB, so I can't (easily) set it up with a keyboard. I know I can enable the ssh daemon by editing cmdline.txt before inserting the SD card into the Pi. In theory I could then complete the setup remotely. Unfortunately, the Zero W also does not have ethernet, so I can't get it one the network without WiFi connection details.
Is there any way I can pre-configure the WiFi on the SD card before inserting it into the Pi so that it is enabled as soon as the Pi boots for the first time? I know Raspbian and other distros allow you to place wpa_supplicant.conf into /boot on the SD, but last I checked LE doesn't use wpa_supplicant.
Alternately, does anyone have any other suggestions? I was also hoping I might be able to use a remove via CEC - and the adapter does pop up as discovered - but I can't seem to use it navigate the setup screens. From memory, the same remote has worked on other LE boxes post-setup.
