@ -103,19 +103,6 @@ sudo hostnamectl hostname "localhost"
An empty (blank) hostname is also an option, but a static hostname of "localhost" is less likely to cause breakage. Both will result in no hostname being broadcasted to the DHCP server.
### Disabling transient hostname management {#rmhostname-transient}
It's best to create a dedicated configuration file, such as `/etc/NetworkManager/conf.d/01-transient-hostname.conf`, to ensure package updates do not overwrite the configuration:
```
[main]
hostname-mode=none
```
This will prevent NetworkManager from setting transient hostnames that may be provided by some DHCP servers. This will have no visible effect except with an empty static hostname.
After editing the file, run `sudo nmcli general reload conf` to apply the new configuration. Run `sudo hostnamectl --transient hostname ""` to reset the transient hostname.
