Unfortunately there are no docs, as the Raspberry Pi is not an actively used platform for router7 (I switched to the apu2 after prototyping). That said, your guess is likely correct, this gokr-packer invocation should do the trick: gokr-packer \ -hostname=router7 \ -overwrite=/dev/sdb \ -gokrazy_pkgs=github.com/gokrazy/gokrazy/cmd/ntp \ github.com/rtr7/router7/cmd/... But note that you might need to rebuild https://github.com/gokrazy/kernel https://github.com/gokrazy/kernel with some additional kernel options from https://github.com/rtr7/kernel https://github.com/rtr7/kernel, plus options for whichever USB ethernet adapter you’re going to use. Note that you won’t have automated recovery (rtr7-recover), as that uses PXE boot, which Raspberry Pi’s don’t do by default (and rtr7-recovery-init has some hard-coded values which won’t work on the Raspberry Pi, at least not when using an SD card for storage).
