## Predictable network interfaces
|
|
|
|
|
|
|
|
|
|
### systemd.link
|
|
|
|
|
Get back the "old" interface names like `eth0` or `wlan0` with
|
|
|
|
|
[systemd.link](https://www.man.page/5/systemd.link).
|
|
|
|
|
|
|
|
|
|
This might be useful, sometimes.
|
|
|
|
|
### Ethernet
|
|
|
|
|
|
|
|
|
|
<https://www.freedesktop.org/software/systemd/man/latest/systemd.link.html>
|
|
|
|
|
This makes my ethernet interface be called **eth0** again.
|
|
|
|
|
|
|
|
|
|
Create `/usr/lib/systemd/network/80-ether.link` with this content:
|
|
|
|
|
|
|
|
|
|
~~~systemd
|
|
|
|
|
[Match]
|
|
|
|
|
Type=ether
|
|
|
|
|
|
|
|
|
|
[Link]
|
|
|
|
|
NamePolicy=keep kernel
|
|
|
|
|
~~~
|
|
|
|
|
|
|
|
|
|
Reboot.
|
|
|
|
|
|
|
|
|
|
### Wireless
|
|
|
|
|
|
|
|
|
|
This makes my wireless interface be called **wlan0** again.
|
|
|
|
|
|
|
|
|
|
Create `/usr/lib/systemd/network/80-wlan.link` with this content:
|
|
|
|
|
|
|
|
|
|
~~~systemd
|
|
|
|
|
[Match]
|
|
|
|
|
Type=wlan
|
|
|
|
|
|
|
|
|
|
[Link]
|
|
|
|
|
NamePolicy=keep kernel
|
|
|
|
|
~~~
|
|
|
|
|
|
|
|
|
|
Reboot.
|
|
|
