Bug 874735

need to know who is using these facts, and if changing it, or adding new facts with related info (for example, something like net.interface.eth0.ipv4_net_addrinfo = {'127.0.0.1', '255.255.255.0'})

Is anyone parsing or using the infomation currently in these facts. Would
changing this break stuff?

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Acking 7.1

This feature request was not implemented and delivered to QE by the rhel-7.1.0 Dev Freeze date of 10/27/2014.  Deferring for consideration in next release.

A new fact should be created (such as net.interface.eth0.ipv4_net_addrinfo_list) that has the new format and the existing fact should remain the same. In that way, if someone is using the existing fact the format will not change on them.

VERIFIED: All of the facts above whose names end in "_list" are the new facts introduced by this RFE.  Notice that all of them are currently a list of 1 value which is equivalent to the prior fact and occur for each of the ipv4 and ipv6 network devices I currently have defined (eth0,lo,virbr0).  A list of 1 is expected when there is only one net interface address configured.

Admittedly I am not an expert at networking.  But I'll do my best to configure a second address for one of my devices and list the facts again to demonstrate a list....

1. call "route -n" and look for the line with Flag UG and take note of the gateway for setting below (10.16.7.254)

2. start application "gnome-control-center network&"
On my "Wired" network I clicked the gear icon button
chose "Identity" in the left list to find the Name of the interface (eth0)
chose "IPv4" in the left list
changed Addresses from "Automatic (DHCP)" to "Manual"
set Address 192.168.1.1
set Netmask 255.255.255.0
set Gateway 10.16.7.254
click the + button to add another ip address
set Address 192.168.1.2
set Netmask 255.255.255.0
set Gateway 10.16.7.254
click Apply

3. systemctl restart network.service

4. subscription-manager facts --list

VERIFIED: All of the net.interface.eth0.ipv4_*_list facts now show a comma delimited list of configured addresses (2) where the last list value equals the prior non-list fact value

PS. I don't know how to add a second ipv6 net interface address.  NEEDINFO
