I just installed 19 on a system with a H67 Intel board, Sandy Bridge CPU, and WDC IDE drive using a IDE/SATA adapter.

It was slightly disconcerting to see the following behavior: after installing 19 on a wiped drive and selecting the option to download updates and reboot, to see the screen turn almost black and stay that way, with no disk activity indicated by the LED on the case. Perhaps this is a bug.

So after some time, I forced a reboot with the case switch. After the BIOS screen, I saw two entries: Fedora and a rescue option. The rescue option is now more obvious than in 18.

Then I installed outstanding updates. After it completed, I rebooted, only to see three lines after the BIOS screen: 19, Fedora of some sort, and the rescue option. So every time updates are installed will we see another boot option of a Windows-esque restore point? If that is the case, I recommend that the text be much more descriptive and readable.

Could you upgrade the title to make it more representative of your question?

By default, Fedora keeps the three most recent kernels, so that you have the most recent one and two backups in case the newest one crashes, or otherwise doesn't work for you. Once you have that, Fedora will remove the oldest kernel every time it installs a new one.

Thanks for all of the answers. Sorry for the strange title, as I was caught up in cat humor.

What you're seeing there is a rescue boot option. When Fedora boots, it uses a relatively small read-only filesystem called an initramfs, which contains the tools and programs required to bring the machine from initial loading of the kernel to the fully featured operating system.

Starting with Fedora 19, that initramfs contains only the programs and tools required for your specific system. Boot is faster because you don't load things that you don't use.

Read http://docs.fedoraproject.org/en-US/Fedora/19/html/Release_Notes/sect-Release_Notes-Changes_for_Sysadmin.html#idm263809153904 for more information.
