JunOS Devices

Look into ZTPing JunOS devices

With JunOS you can provide it a firmware + config, alternative a script

With a script like below, it would be possible to get the serial number, then attempt to load the config from NetZTP based on that serial

#!/bin/sh

SERIAL_NUMBER=$(/bin/sh -c "cli show chassis hardware | grep Chassis" | awk '{ print $2; }')
/usr/sbin/cli -c "configure; load override http://ztp.example.com/junos/$SERIAL_NUMBER; commit"

We can likely just use Python instead of SLAX and not support devices older than 16.x (when Python support was added), this would allow us to use PyEZ to do RPC calls to get the serial number, load config from URL, etc
