@georgejhunt can you please tell me if the following 3 lines are still needed? (Y/N)

py_captive_portal_port: "9090"
py_captive_portal_username: "Admin"
py_captive_portal_password: "changeme"

Is roles/network/defaults/main.yml the right place for them if they're still needed? (@tim-moody suggests this is not the right place for py_captive_portal_* variables?)

@jvonau to solve the Ubuntu 18.04 problem arising from iiab_network_mode: Appliance are you recommending fallback value dhcpd_service2: disabled be initialized around line 72 of https://github.com/iiab/iiab/blob/master/roles/network/defaults/main.yml#L72 ?

Smoke-tested on Ubuntu 18.04

Let's refine further...e.g. during our Tuesday 10AM NYC Time community/team call (http://minutes.iiab.io)
