Binary package “userv” in ubuntu kinetic

`user services' - program call across trust boundaries

 userv allows one program to invoke another when only limited trust
 exists between them. It is a tool which can be used to avoid having
 to give other system services root privilege, and which allows users
 to more securely have programs provide services to others.
 userv can be useful as `glue' for system administrators; there are
 not many full-blown userv-using applications yet.
