The devices get umount'd in the wrong order. In later versions of
livecd-creator we changed things so that lazy umounts are used.
I think there is still a place where an exception can occur where things
don't get cleaned up nicely, but for the most part exceptions don't
leave lots of stuff mounted these days.

I am not sure how well livecd-creator for recent Fedoras will work on CentOS
5.
