Exactly. I'd not thought of the acls issues, but yes, they should be  
invariant if possible.

I suppose this brings up some other issues as well. For example,  
would we want a -readonly flag for 'vos copy' so one could make an  
invariant copy of an existing volume? I can see some use for that.  
And I suppose we'd want 'vos convertROtoRW' to work as well.

Since '.readonly' has such a strong association with replicant  
volumes, perhaps we should refer to this new type as an invariant  
volume. The different terminology will prevent a lot of confusion.
