KNoppix modified my root name

[mepouze]

yes I used the dvd of knoppix

What I forgot to precise is that I used the version 5.1.1 of knoppix CD, not dvd.
So now, i'm thinking about many things : maybe the 5.1.1 CD Boot is too old and presents uncompatiblities with the news OSes like centos 5.5 GUI.
Maybe I will have to format my disk in fat32 in order to clean it totally.
I need some help to conclue =p
