Thus in this case, the interesting aspect of PAGG is not the "container"
aspect but it's the "hook manager" aspect, right? 

PAGG has only a callback for "exec" and not for "fork". So, if you want
to use PAGG has a common hook in "fork" for several applications, we
need to add new hook (like pagg_fork in kernel/fork.c:do_fork()). 

Is it be possible to split PAGG into two pieces: 
    1. The container manager part 
    2. The hook manager part
