ChatGPT gave the following. Follow at your own risk. Most important is to check if the file locations are compatible with Fedora.

To automate running the update-grub command after each kernel update, you can create a script and set it up to run automatically. Here's a more direct approach:

1. Open a text editor and create a new script file. For example, you can name it "update_grub.sh".

2. In the script file, add the following lines:

   #!/bin/bash
   /usr/sbin/update-grub
   

3. Save the script file in a location where it can be easily accessed, such as your home directory.

4. Make the script executable by running the following command in the terminal:

   chmod +x /path/to/update_grub.sh
   

5. Next, you can set up a cron job to run this script automatically. Open your crontab file by running:

   crontab -e
   

6. Add a new line at the end of the crontab file to schedule the script to run after each kernel update. For example:

   @reboot /path/to/update_grub.sh
   

7. Save and exit the crontab file.

With these steps, the update-grub command will be executed automatically after each kernel update, ensuring that the new kernel version boots successfully.
