Fedora / Manjaro – Change Hostname – Var 1

Open a Terminal: Launch a terminal in your Manjaro system.
Change the Hostname: Use the hostnamectl command to set the new hostname:
```
sudo hostnamectl set-hostname new-hostname
```
Replace new-hostname with the desired hostname.
Verify the Change: To confirm the new hostname has been set, run:
```
hostnamectl
```
This will display the current hostname along with other system information.
Edit /etc/hosts (Optional but Recommended):
- You should still update the /etc/hosts file to ensure proper hostname resolution. Open the file with:
```
sudo nano /etc/hosts
```
- Update the line containing the old hostname to the new one:
```
127.0.1.1   new-hostname
```
- Save and exit.
Reboot the System (Optional): While the hostname change takes effect immediately for many operations, a reboot ensures all services recognize the new hostname:
```
sudo reboot
```

This method is straightforward and effectively changes the hostname system-wide.
