The NFS export scripts and such expect the pseudo DB to be available to them. 
The filesystem can be anywhere the user wants, so somehow we have to know where 
it was extracted, and the only answer we came up with at the time was to put the 
pseudo database into the filesystem directory.  It doesn't cause any harm to the 
target that is being booted, and it ensures that the NFS server setup scripts 
know where the both the root and pseudo DBs are located.
