No idea about your problem, but ezjail is already doing some dedup.  
The basejail is the dedup-place, and the jails do a null-mount of it.  
Inside the jails are only some links to the basejail. So if you do not  
install the same programs (the same packages, so make sure there is no  
different compile timestamp (some programs have this) inside the newly  
generated binaries) or data inside the jail-specific area, you will  
not have a benefit from this.

Bye,
Alexander.
