Base setup

Warning: the OpenWRT web UI backup process only includes a portion of the /etc directoy. Back it up manually to preserve any customizations done outside of uci/luci.

Flash the 64 EFI variant of the latest OpenWRT version.

Specifically, the x86-64-generic-ext4-combined-efi variant.

dd if=openwrt-21.02.0-x86-64-generic-ext4-combined.img bs=1M of=/dev/sdX

Arch can run k0s in a relatively stable way.

Initial setup requires:

• Installing htop, openssh, nano, dhcpcd.
• Manually adding localhost in /etc/hosts.
• Setting the node's hostname in /etc/hostname.

Enable core services:

Download FW package and start TFTP server. I used uftpd on Debian.

Generate CCODE using AP's serial number:

echo -n "<CC>-<SN>" | sha1sum | tr -d " -"

Concatenate the resulting string with the following format:

CCODE-<CC>-<SHA1SUM_CODE>
