The reboot is what I am planning to do, but I prefer to look first at a 
better option instead of settling for this because I don't know better :-)

I fear that anaconda's data-structure is not updated and the scan for 
disks has already happened before the %pre. Because after my RAID scripts 
has run, I do have /dev/sda available to the system, but anaconda behaves 
as if there were no disks found.
