Comment 23 for bug 132311

>Those old kernels can often be useful when there is a regression.

i doubt there will be much regressions in kernels of the same minor version ever.
especially ones which render kernel unbootable.

>I can't remember how many times having the old kernel around has saved my bacon.

keyword will be "old kernel" - 1 is fine, especially if it's one from which update has been made.

>For experienced users and those who participate in alpha testing,

good for testers, not users.

> I think having those kernels around is very important.

and i do not think so even for testers since they pretty much capable of reverting back after unlikely critical failure even if both "new" and "worked" kernels are broken by having 100% working version preinstalled manually or booting from live system or kernel from external device with initrd and 'root=<ubuntu root>' option

>Those folks won't mind all the extra lines of gibberish.

those folks can handle a lot of crap life can throw at them, i have no doubt about that.
but, being gentoo user myself, i do not appreciate useless stuff lying around even though i reboot my home systems no often then once per 2 weeks. and i cannot comprehend how it can be frustrating for "normal people"

new grub2 widget-like graphic menu may look fancy but probably will not include any crutches for hiding ranges of kernels with same root-option. just keep it simple, please :(

PS: "people" do not report two issues here, it just someone with too long hands is marking reports about menu and space as duplicates :\ but since those useless kernels clutter both menu and space it better to "kill two hares with a single shot"
