If you look at something like fedora images, its something like fedora Linux 7.13.1-201.x64.f44, And this only gets worse once you get to something like the surface kernel

So probably it will shorten the names to something like Fedora Linux, but then you won't know what you want to select if anything goes wrong

What I mean is that boot managers are like static friction: it's a theoretical thing that simply does not impact you as long as youre moving, until the moment you stop at which point it becomes real and starts pushing back as strongly as you configured them to be

Just make your grub wait 3 secs before booting, it isn't worth saving that one press on the enter key
