Hi Chris!

At least I'm not able to copy through my partition via "cp -a ..." with 
the last supposed setup + preempt without quota ...

When umounting the destination partition it says "device is busy".

I don't know what is gone for now on my repository partition, but I know 
from earlier times this should not happen.

Bye,

Manuel
