A new event type doesn't change the architecture ... if
that's all that's needed, the architecture is unchanged!

To some folk, it won't even matter if the event comes from
a devfsd thread or a kernel thread.  Implementation detail.
Except maybe to the US Patent Office ... sigh.  (One
iteration of USB hotplugging did just that:  devfsd called
the same policy scripts as the kernel thread version.)

Yep, lots of tools to choose from.  But again, not everyone
runs supermount (or wants to) -- Yet Another Daemon, as I
recall the situation.
