Nefungujici prejmenovani ethernetovych interface (bezstarostna beznadej)

["Zdeněk Kaminski"]

Dobry den,

 pouzivam ve virtualu rhel7 a systemd-udevd mi prejmenovava ethernety tak,
jak uzna za vhodne on, nikoliv, jak se mu snazim podstrcit ja. Nepouzivam
NetworkManager, neni na systemu nainstalovan. V
/etc/sysconfig/network-scripts/ nemam zadne soubory ifcfg-eth*.

Takto to vypada po bootu bez jakehokoliv  zasahu do konfigurace v
/etc/udev/rules.d/

vypis z /var/log/dmesg:
[   10.621329] 8139cp 0000:00:03.0 eth0: RTL-8139C+ ...0:cf:98:d7, IRQ 11

[   11.984407] systemd-udevd[268]: renamed network interface eth4 to ens9

Pokud do /etc/udev/rules.d/ pridam soubor 70-my-net-names.rules s obsahem:

SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="52:54:00:cf:98:d7",
NAME="haf0"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="52:54:00:f4:d8:30",
NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="52:54:00:f4:d8:31",
NAME="eth1"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="52:54:00:f4:d8:32",
NAME="eth2"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="52:54:00:f4:d8:33",

SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="52:54:00:f4:d8:34",
NAME="eth4"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="52:54:00:f4:d8:35",
NAME="eth5"

dopadne to takto:
[   11.009789] 8139cp 0000:00:03.0 eth0: RTL-8139C+ ...0:cf:98:d7, IRQ 11

[   11.967330] systemd-udevd[268]: renamed network interface eth0 to haf0

Neboli prvni interface mi prejmenuje tak, jak potrebuji a na ostatni se
vyprdne.

Pokud vsak soubor 70-my-net-name.rules prejmenuji na 81-my-net-name.rules
(81 proto, protoze /usr/lib/, dopadne to takto:

[   11.734303] systemd-udevd[270]: renamed network interface eth0 to haf0
[   11.777254] systemd-udevd[271]: renamed network interface eth1 to eth0
[   11.789383] systemd-udevd[274]: renamed network interface eth2 to eth1
[   11.880320] systemd-udevd[276]: renamed network interface eth3 to eth2
[   11.890343] systemd-udevd[266]: renamed network interface eth4 to eth3


Jak to, hernjas? Snazil jsem se postupovat podle
http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/
a prd Velebnosti :-(
