No, upgrading F15 is a pain. Beware, expect danger!

System 1: I tried to upgrade one system using the install DVD. Upon 
rebooting, I got a blank screen with a flashing cursor. Not even grub! A 
fresh install (overwriting everything) fixed that, but still...

System 2: I tried it on a second system, using both the Live CD and the 
install DVD. I got further, but gdm crashed when trying to log users in 
(https://bugzilla.redhat.com/show_bug.cgi?id=707985, 
https://bugzilla.gnome.org/show_bug.cgi?id=651180). I found a workaround 
for that, but the system was super-unstable and prone to long freezes. 
Swapping in different video cards and ethernet cards didn't fix it, so I 
had to revert to F14 on that system.

System 3: I used preupgrade-cli with vnc, but it wouldn't boot into 
anaconda - another black screen with a flashing cursor. Going to the 
second grub choice landed me safely back in F14.


I'm kind of sad, because I actually really like gnome-shell now! It has 
quirks, but they'll get ironed out soon enough...

This will be a slow roll-out here, based on results so far :-(
