That is one of the wonderful things about unix!  Multiple physical disks
which may contain multiple logical partitions can be mounted together into
one huge filesystem. 

I think that you are thinking of the more complex matter of making
multiple physical disks appear as one large physical disk. (As in
Netware 3.x, for example).  It CANNOT do this.  You cannot have files
that exceed the size of the single physical disk or partition.

One more time, the partition on the 2nd disk CANNOT be another file-system
it must be mounted onto the /root filesystem forming one large, physically 
transparent filesystem.
