this is pure Debian base image of Buster without GUI and another stuff. Image doesn’t contain anything from Armbian, there is no tools from Armbian, only pure Debian installed via serial line. This image is primary for mhog but feel free to test it too, and please report your testing If there is no support from Armbian anymore, then I am looking for another source.
Kernel : 4.19 as same as in production Debian
hostapd : there is original hostapd from debian, for newer kernel is not needed hostapd-realtek
Swap was disabled, vm.swappiness is set to 0 (it is a pitty idea IMHO)
legacy naming of interfaces was enabled (wlan0) and output is enabled for serial line and HDMI
realtek fw was installed from non-free
all repos was enabled : main non-free contrib
ondemand governor was setted on cpufreq
dhcp client and openssh server enabled on eth0 …
This image is only for test, please… there is no support and I tested it only 24 hours with stress.
resize of image is possible to do by fdisk :
