Aaron, thank you for your suggestion. For now I prefer to try to use the oldest suitable hardware I can find, not sure if it is a good idea.
Please someone let me know if AllWinner SoC backdoor described at: https://www.theregister.co.uk/2016/05/09/allwinners_allloser_custom_kernel_has_a_nasty_root_backdoor/ can be exploited in OpenBSD? Is it a bad idea to run a small communication server on a AllWinner A20 board like a Cubitruck if it works with OpenBSD (it is not on the list though). What about other compatible boards like AllWinner A10 Orange PI One? I just want my DNS (local) and postfix, dovecot (Internet) and SSH (local and Internet) work on it protected from hackers.
