jails share the kernel but not the world.

So, there will be only one kernel loaded but all libraries in use 
will be loaded individually by each jail when needed.

Jails need some more disk space as the world, all libraries needed 
and all applications needed are installed individually in each 
jail.

This can be minimised with proper planning of what runs it what 
jail.
