Building: Make a build.cfg file and run ./build.sh:
pxeUrlPrefix https://yourdomain.com/pxe-images
pxeUrlSuffix netboot.ipxe
packetKey your-packet-api-key
packetDevice your-packet-device-id
buildHost user@an-aarch64-capable-build-box
imageName nixos-packet-aarch64-2018-01-03v1
pxeHost user@web-accessible-server
pxeDir /path/to/web/root
The build will happen on buildHost then copied directly from buildHost
to pxeHost:pxeDir/imageName (via netcat and openssl).
If the destination directory already exists, it will be overwritten.
Update the PXE url and restart the server with ./restart.sh. The PXE
URL will be calculated by pxeUrlPrefix/imageName/pxeUrlSuffix.
