I tried installing the fc5 test package and it failed. It would not boot in 
text mode (linux text). I booted it in graphic and got to the package 
selection having configured all kinds of raid. It crashed when I was looking 
at the details of a package, one of the server packages if I remember 
correctly. I then lost most of my raid settings as the install was not 
complete. Maybe I should wait for the next test release before trying such a 
thing unless I get brave one day.
