Environment Variable Parsing

[PromoFaux]

Currently, to pass an array item into an environment variable it needs to look something like:

FTLCONF_dns_hosts: '127.0.0.1 google.com;127.0.0.2 facebook.com'

[dns]
  # Array of custom DNS records
  # Example: hosts = [ "127.0.0.1 mylocal", "192.168.0.1 therouter" ]
  #
  # Possible values are:
  #     Array of custom DNS records each one in HOSTS form: "IP HOSTNAME"
  hosts = [
    "127.0.0.1 google.com",
    "127.0.0.2 facebook.com"
  ] ### CHANGED (env), default = []

This is fine for a couple of values, but gets quite unreadable when you want to add in more.

Another way of passing these in would be:

FTLCONF_dns_hosts: |
    127.0.0.1 google.com
    127.0.0.2 facebook.com
    127.0.0.3 somethingelse.com
    127.0.0.4 you-get-the-point-im-trying-to-make.org

While this looks normal here:

It looks odd in the config file:

[dns]
  # Array of custom DNS records
  # Example: hosts = [ "127.0.0.1 mylocal", "192.168.0.1 therouter" ]
  #
  # Possible values are:
  #     Array of custom DNS records each one in HOSTS form: "IP HOSTNAME"
  hosts = [
    "127.0.0.1 google.com\n127.0.0.2 facebook.com\n127.0.0.3 somethingelse.com\n127.0.0.4 you-get-the-point-im-trying-to-make.org\n"
  ] ### CHANGED (env), default = []

Weird still on the local DNS settings page:

However the actual resolution of these hosts works despite that:

Is there something we can do to pretty this up a bit?
