You are right, a refresh is needed at some point but it may not be desirable to do it just then. Bear in mind that an admin always has access to other methods to perform an explicit refresh when the time it's suitable (e.g. Felix shell) for them. FileInstall is, in fact, a secondary mechanism.
In my opinion, it would make for a more powerful FileInstall if one could configure whether refreshes will be immediate, or are left up to the user. Agreed that FileInstall is not the best approach for production. Regards, Raúl.
