In the end it turns out that even with "unmanaged" via NetworkManager's
'ifcfg-rh' plugin(NM_CONTROLLED=no) the whole thing is broken.
If the systemd-networkd is running side by side with NetworkManager,
trying to drive the "unmanaged" devices, both services collide and the
network is cowabungad. It only works if the one of the services is
offline, no tricks.
So the story of the synergy of these two tools is just a theory, for now.
How the 'NetworkManager' is configured:
$ ls /etc/sysconfig/network-scripts/ifcfg*
ls: cannot access /etc/sysconfig/network-scripts/ifcfg*: No such file or
directory
$ ls /etc/NetworkManager/
conf.d dispatcher.d dnsmasq.d NetworkManager.conf system-connections
VPN
$ ls /etc/NetworkManager/system-connections/*
ls: cannot access /etc/NetworkManager/system-connections/*: No such file
or directory
$ file /etc/NetworkManager/NetworkManager.conf
/etc/NetworkManager/NetworkManager.conf: symbolic link to
`conf.d/keyfile-plugin.conf'
$ cat /etc/NetworkManager/conf.d/keyfile-plugin.conf
[main]
plugins=keyfile
[keyfile]
unmanaged-devices=interface-name:enp3s0
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
How the 'systemd-networkd' is configured:
https://bugzilla.redhat.com/attachment.cgi?id=877526
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
After the system boot:
$ systemctl is-enabled NetworkManager systemd-networkd
enabled
enabled
$ systemctl is-active NetworkManager systemd-networkd
active
active
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Dan served cold appetizer:
$ ps -o %cpu $(pidof NetworkManager)
%CPU
0.0
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Something boiling in the Tom's kitchen:
$ ps -o %cpu $(pidof systemd-networkd)
%CPU
66.3 and still rising!
~~~~~
After turning on the cooker hood,
# systemctl restart systemd-networkd.service
everything is OK again:
$ ps -o %cpu $(pidof systemd-networkd)
%CPU
0.0
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
How the pots are stored by Dan's recipe:
$ nmcli device
DEVICE TYPE STATE CONNECTION
bridge0 bridge disconnected --
enp3s0 ethernet unmanaged --
$ nmcli device show enp3s0
GENERAL.DEVICE: enp3s0
GENERAL.TYPE: ethernet
GENERAL.HWADDR: 00:12:34:56:78:30
GENERAL.MTU: 1500
GENERAL.STATE: 10 (unmanaged)
GENERAL.CONNECTION: --
GENERAL.CON-PATH: --
WIRED-PROPERTIES.CARRIER: on
$ nmcli device show bridge0
GENERAL.DEVICE: bridge0
GENERAL.TYPE: bridge
GENERAL.HWADDR: 6E:DC:CC:FF:82:3D
GENERAL.MTU: 1500

$ nmcli connection
NAME UUID TYPE DEVICE
bridge0 b59e371b-a7cd-4961-a16a-714e2f7d4a84 bridge --
~~~~~~~~~~~~~~~~~~~~
Sometimes like this:
$ nmcli device
DEVICE TYPE STATE CONNECTION
bridge0 bridge connecting (getting IP configuration) bridge0
enp3s0 ethernet unmanaged --
$ nmcli device show bridge0
GENERAL.DEVICE: bridge0
GENERAL.TYPE: bridge
GENERAL.HWADDR: 06:EC:EB:15:92:5F
GENERAL.MTU: 1500
GENERAL.STATE: 70 (connecting (getting IP
configuration))
GENERAL.CONNECTION: bridge0
GENERAL.CON-PATH:
/org/freedesktop/NetworkManager/ActiveConnection/0
$ nmcli connection
NAME UUID TYPE DEVICE
bridge0 810af447-0948-4d54-b72b-4c8085bcbc10 bridge bridge0
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
But the real fun starts after opening discotheque:
# systemctl restart NetworkManager.service
$ nmcli device
DEVICE TYPE STATE CONNECTION
bridge0 bridge connected bridge0
enp3s0 ethernet connected enp3s0
$ nmcli device show enp3s0
GENERAL.DEVICE: enp3s0

In the rhythm of the "Smashed Potato Soup"! :)

To the beat of the rhythm of the night
Dance until the morning light
Forget about the worries on your mind
You can leave them all behind
Oh yeah
