I finally battle tested my BananaPi RPI-R3 with #OpenWRT. After a long time I am configuring weird network staffs (#yggdrasil, #xray and etc) without my beloved #nix. GUI configs sometimes really cosy... before you need something unusual (ALWAYS for me).
I also tried #nixos (bless nixos-sbc), but it's not cool to write #uboot to SD card or ssd. I need to try something like a generic UEFI boot loader on onboard eMMC. Ideally secure boot, but I don't think I have anouth mana for that kind of magic
