1) Fedora Project does not formally support the XFS filesystem. It is pretty much provided as it for migration reasons. Ext3/Ext2 and GFS filesystems are the only on disk filesystems supported
Rahul: XFS worked on FC4... Actually quite solid, I used it for close to one year...
Does it make sense to drop a feature, which is quite nice?
2) You might want to discuss this in fedora-test list and file a RFE in Anaconda. Might be too late for FC5 now but subsequent version can have this feature.
I will look at tit, but the fedora bug reporting system (as forums) is not simple to use!
Why so many menus, acces etc... It looks like "they" do not want bugs to be reported!
3) GNOME is default largely because Fedora Core/Red Hat has more expertise on it. Since both is supplied by default in Fedora Core you have the freedom to choose either one of them. Long term plans and proposals are available in http://fedoraproject.org/wiki/KDE
OK this is a long discussion, whenever Novell decided to drop KDE for GNOME, lots of users complained.
As a user, I have a trong preference for KDE: it is just a better user's interface, easier to use, configure, modify etc...
As a programmer is GNOME better to the point RED-HAT programmers prefer it?
Also I tend to believe that most Linux distros will do better with KDE than without!
Not wistanding the current succes of UBUNTU (with "geeks), KUBUNTU may be successfull.
Here to: FC4 worked just fine (a bit slow) with KDE....
Unless clearly I would expect FC5 to have the latest KDE (3.51?)
