Relevant to bug 134638 and 223673:Modified anaconda so the user could have some way of striping his lvs (It only works for graphical installations). The patch changes more things than I would want to. And more likely introduces more bugs to the code than it takes out. But I think it might be a nice work around for the time being. The files and diffs are in https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=134638.
