Hi,

Accessing fw_cfg after migration is fine. Problem is this ...
(1) read directory
(2) migrate
(3) read file
... in case the file ordering happens to be different on the destination
host due to initialization order changes.
So, sorting entries (and the index assigned too) should fix this, right?
That looks easiest to me.
cheers,
Gerd
