Usability Improvement: Avoid Rebooting into Installation Medium and Allow Configurable Finish Module Text in Calamares

[adrelanos]

Is your feature request related to a problem? Please describe.

At the conclusion of the installation using the Calamares installer, the finish module prompts users to reboot the system. A potential issue arises when users reboot with the installation medium, like a DVD or USB ISO image, still connected. This often results in the system booting from the installation medium again rather than the installed system. While Debian's older d-i installer used an eject command to prompt the removal of DVDs, there is no equivalent method for USB devices, leading to potential confusion.

Describe the solution you'd like

I propose the following enhancements to the Calamares finish module:

1. Introduce configurable text to better guide users during the final installation steps.
2. Provide an option to shut down (power off) the system instead of rebooting, allowing users to manually remove the USB device before powering on again.

This approach aims to clearly inform users about the need to remove the installation medium before restarting their system.

Describe alternatives you've considered

Alternatives include:

1. Modifying the Calamares finish module to issue a poweroff command instead of a reboot.
2. Developing a custom Calamares module that provides textual information, running it just before the finish module.
3. Improving the hardcoded text within the existing Calamares finish module to offer a clearer explanation of the steps users should take after installation.

This can already be controlled by the finished.conf, at least controlling the buttons and their actions. As per the text, why is this really necessary?

The finishedq module gives you all the options to create custom text/layout/buttons ((create your own QML file).

Not good to change restartNowCommand: "systemctl -i reboot" to restartNowCommand: "systemctl -i poweroff" if the text is still the same.

As per the text, why is this really necessary?

Necessary to explain the issue which I describe in my original post.

The finishedq module gives you all the options to create custom text/layout/buttons ((create your own QML file).

The following code seems hardcoded.

https://github.com/calamares/calamares/blob/calamares/src/modules/finished/FinishedPage.cpp

            ui->mainText->setText( tr( "<h1>All done.</h1><br/>"
                                       "%1 has been installed on your computer.<br/>"
                                       "You may now restart into your new system, or continue "
                                       "using the %2 Live environment.",
                                       "@info" )
                                       .arg( branding->versionedName(), branding->productName() ) );

Message "You may now restart into your new system, or continue " seems hardcoded.

There is no QML file in this folder:

Pretty much all view modules have a qcounterpart:
