I was referring to this clause in the man document:

Descendant jails inherit the parent jail's devfs ruleset enforcement.

I thought that the outside rule is combined with the inside rule in the 
jail definition. But thanks for the hint about jls -s, it does shows the 
(single) active rule set (however without referring to the specific 
rules defined in devfs.rules or a combination of it).
