    I'm testing checkpoints for the 32bit linux 2.4
    kernel.  I'm using two hosts with identical hardware
    and images.  I'm trying to make sure that I can
    restore checkpoints between hosts.  
    
    I noticed that although the basic counting example can
    be checkpointed on host0 and started on host1, my
    custom Matlab code cannot.
    
    System messages suggested the restart failed because
    the /tmp/hsperfdata_user directory didn't exist on
    host1.  After copying this directory between hosts,
    the restart worked properly.  
    
    I'm wondering if it is safe to do this before I put it
    in widespread use.  Are there any other system files
    that should be copied also?  What is the hsperfdata
    directory?  Can this information be stored in the
    checkpoint itself?
    
    Thanks,
    
    Mike
