I get it. That solves the mystrey concerning hda16. But why can't I mount the 
LVM partitions from the rescue environment when they get mounted during a 
normal boot. I had a look at the boot script and it does the same thing as 
I'm doing manually from rescue. Even if an upgrade will solve that problem 
too I am a bit curious about what causes vgscan to fail in the rescue 
environment.
