Yesterday, after some weeks of using Fedora 9-preview, I downloaded the final release. The first thing I did was to create a persistent liveusb --Yes! There's now persistence! officially, at least. The procedure is ridiculously simple, I just typed the following command as root:

livecd-iso-to-disk --overlay-size-mb 512 /path/to/live.iso /dev/sdb1

Now, the overlay size cannot exceed 2048 MB, so if you want to use a bigger usb stick, you'd probably want to have two partitions, so that you can use the rest of the space as a normal stick (both, from within the live system and from any other system.)

... 

The second thing I did was boot the persistent liveusb on my Sony Vaio UX (micro pc). It worked flawlessly, and fast! Even my touchscreen worked almost perfect --I still don't know how to callibrate it, if at all possible. I customized my liveusb and then, when it was already the way I like it, I installed Fedora on my UX. The installer threw a warning saying that if I wanted to use the usb to install Fedora I should re-initialize it, thus, erasing every change I'd made. This warning is a little bit ambiguous, I didn't know if it meant that I couldn't use the usb as installation media or that I couldn't install to the usb (yet again...). So I chose to ignore the warning and go on. The installation went smoothly after that --so I think it meant I cannot install on the usb without re-initializing--, and when finished I rebooted to test and customize the installed system on the UX.

The third thing I did was to install on my normal laptop. Everything was pretty much the same, except that I have a Nvidia card on that pc and the proprietary driver doesn't work with the Xorg version that Fedora 9 is shipping.

Bugs:

My /home partition on my laptop is jfs. Since Fedora 6 I can't tell the installer to use this partition as /home because it crashes at the end of the setup. It didn't change with Fedora 9. I still got the crash.

Packagekit sometimes doesn't show results when I query on something (more specifically, when I click on "gnome" on the categories)

With the Packagekit gui it is only possible to install one package at a time.

My mouse cursor disappeared after logging out and switching to a console and again to X. This happened twice. And twice I had to reboot.

Not-really-a-bug: When using kernel-modesetting (with intel graphic cards (945GM in my case)) I can't use compiz.

Not-a-bug: I wonder what happens when I perform a kernel update on my live-usb...
