Unexpected reboot after powerpc install

[Jeffrey Walton <noloader@gmail.com>]

Hi Everyone,

I was trying to follow John Paul Adrian Glaubitz instructions for
installing Debian 10 on a PowerMac G5. The instructions are at
https://lists.debian.org/debian-powerpc/2021/02/msg00011.html. The
instructions say to forgo the reboot after installation and perform
some extra steps.

At the end of the installation, the last screen told me a reboot was
needed. The last screen gave me two choices - <Continue> or <Go Back>.
I selected <Continue> because I had the extra steps to perform. I
planned on reboot after performing the extra steps.

<Continue> unexpectedly rebooted the machine and I lost the chance to
perform the extra steps. (Now I'm stuck at an OpenFirmware prompt that
results in a kernel load failure/corrupt image error message for every
command I enter. Sigh...)

>From a UX perspective, the last screen has a lot of opportunity for
improvement. There's no indication what <Go Back> does or where it
"goes back" to. It is also not clear that "going back" does not undo
the most recent steps performed by the installer. Finally, there's no
indication <Continue> will immediately reboot the machine.

I believe the last screen should say something like:

    Installation is complete. A reboot is required.
    If you select <Yes> then a reboot will happen now.
    If you select <No> then you will have to manually
    reboot later.

    Would you like to Reboot now?

    <No>            <Yes>

Changing the text on the last screen will dramatically improve the UX
experience. It tells the user what is going to happen. It also offers
the user a chance to avoid the reboot .
