Comment 3 for bug 1630636

@LaMont:

maas: [wget, '--no-proxy', ''http://[2001:67c:1562:8010::2:1] ...

That is telling us something very interesting:

'{{node_disable_pxe_url|escape.shell}}'

should end up like:

'http://[2001:67c:1562:8010::2:1]'

However, the bug is that the URL is returning:

''http://[2001:67c:1562:8010::2:1]''

That said, the original fix included:

31 + return compose_URL(
32 + "http://:8000/", get_maas_facing_server_host(
33 + node.get_boot_rack_controller()))

So I /think/ this will return the URL without the extra quotes ''.
