Description of problem: I’d like to see the list of kernels during bootup and might need to for a problem and the GUI is helpful.

Version-Release number of selected component (if applicable): 40.0

How reproducible: Always.

Steps to Reproduce:

1. Do this when your system has at least two kernels, one of which can be a rescue kernel. If you don't have a rescue kernel, do this after at least one update that included a new kernel.

2. When your system did not crash, warm-reboot. (Under certain conditions, the GRUB or GRUB-like list of kernels will appear. I don't remember all those conditions, but avoid them for this STR.)

3. Without pressing a key during the boot except to enter a password or other authentication, look for the list of kernels.

Actual results: You can press a key to display the list, but, if you don't press it, like if you forgot it, you can't see the list. You can search the Internet to find out how to edit a boot file so you can see the list, but I spent a lot of time trying this time and found advice for other distros, which may differ, or that was ~5-8 years old and may be outdated. The methods I saw were somewhat complicated, not too hard for me but too hard for most nongeeks, and all of the methods were for the CLI.

Expected results: Gnome Tweaks to have something like Tweaks > Boot where this option, and maybe some other options like how long the display would stay on screen before booting advances, would make configuring easier.

Additional info:

Granted that someone who selects a kernel is likely a geek, doing so generally lands the user in a GUI anyway. Since they're likely familiar with the GUI, and may not know how to use the CLI unless tutored, this should be a GUI option.

My platform: Fedora 34, kept evergreen, with Gnome 40.

I’m told that Gnome bugs have to go to a distro before being reported to Gnome, so, even though this is a feature request, I'm reporting here first.
