GRUB 2 2.0 landed in Ubuntu 12.10 (by default)

GRUB is Ubuntu's default boot loader and manager, allowing the user, when the computer starts, to select a preferred operating system, a different kernel from an operating system, generate various tests, etc, via a minimalistic clear interface, usually (in Ubuntu) displaying a purple-ish background and text.

Although perceived as GRUB 2, Ubuntu uses (in its at-the-moment current version) GRUB 1.x (1.99 version), 1.99 release acknowledged and referred to across the internets as GRUB 2.

GRUB 2 (the actual "real" 2.00 version) has landed in Ubuntu 12.10, introducing a solid amount of fixes, improvements, under-the-hood changes, etc.

A definitely interesting addition in the new 2.00 release is its manner of dealing with listed operating systems, meaning, starting the computer, presents (when on selecting the about-to-be-started OS) simplified OS names.

The "old" behavior presents Ubuntu, with Linux kernel 2.6.x, the new GRUB2 displays only Ubuntu 12.04.1 (case applicable for Ubuntu 12.04.1 LTS), furthermore, adding an Advanced options for Ubuntu entry, clicking on it exposes all of the available installed Linux kernel versions, entry useful to select an inferior/different kernel version.

Although the mentioned change is minor, the result is highly-effective and definitely a key point for properly selecting an Ubuntu version, especially on multiple-Ubuntu-versions-on-the-same-machine environments managed by newcomers.

Removing (by hiding) the kernel versions, adds an immediately noticeable clarity to the purple-ish screen, yet, users can 1-click away access the available kernels, basically, putting advanced "items" into an advanced (yet "clickable") area.
