f36 ifcfg sub-package

[Tom Horsley]

The description of changes to fedora says built in support
for ifcfg files won't be installed by default but an "ifcfg sub-package"
can be installed to support them.

After peering at "dnf search" results I finally found the actual
name of the sub-package:

NetworkManager-initscripts-ifcfg-rh-1:1.36.4-1.fc36.x86_64

Now I finally have all my complicated bridges and wot-not back and
network functioning as it did on f35.

I don't suppose there is an automated tool to convert complicated
ifcfg files to NetworkManager keyfiles is there?

Yes there is a tool. See this article for details.

Thanks. Once I think everything is working I'll give this a try and see
if everything still works the same.

That article says:

# Starting with Fedora Linux 36, the ifcfg support will no longer be present
# in new installations. If you’re still using ifcfg files, do not worry —
# the existing systems will keep it on upgrades. Nevertheless, you can still
# decide to uninstall it and carry your configuration over to keyfiles. Keep
# on reading to learn how.

However, Tom seems to be reporting that everything broke for him, until he  
hunted down the package and manually installed it.

Reading further into that article, I am informed about "nmcli connection  
migrate".

Checking my F35's man page, there's no mention of this option, so this  
appears to be new in F36.

So, the migration process appears to be:

1) Update F35 to F36

2) After a reboot things will be broken because ifcfg support is gone

3) Run "nmcli connection migrate" to restore network connectivity

Is this correct?

Many moons ago, before this was even recognizable in NM (IIRC), I managed to  
hack together a bridge for a qemu VM. It works, the guest seems to have no  
problem getting its IP address from my DHCP server. After reading that  
article:

$ nmcli -f TYPE,FILENAME,NAME conn
TYPE      FILENAME                                                     
NAME
bridge    /etc/sysconfig/network-scripts/ifcfg-vnet0                  Bridge vnet0
bridge    /run/NetworkManager/system-connections/virbr0.nmconnection  virbr0
ethernet  /etc/sysconfig/network-scripts/ifcfg-eth0                   System eth0
ethernet  /etc/sysconfig/network-scripts/ifcfg-eth1                   System eth1

So, what are the chances that my VM's network connectivity survives  
migration to F36?

It would be useful to have nmcli connection migrate functional in F35, to  
give me some kind of an advance warning…

Only because I installed from scratch then tried to copy all the
config files like I usually do. (I like to keep my working install
intact and install in a different partition and get everything
configured before switching to new version).

On another system I used dnf to do the upgrade from f35 to f36
and that one did automagically install the ifcfg plugin as part
of the upgrade process.
