This risk reopening the old religious war if drivers should poll
their drives to be up to date on media existence.

Practically all other modern operating systems do it, with the
benefit that an icon can be flashed when you plug something in,
(and in certain cases, so viruses can be autoinstalled without
relying on user stupidity).

I personally think it would make a lot of sense if FreeBSD moved
in that way, but I've been told in no uncertain terms that this
will speed up third coming and shake the very foundations of the
unive^H^H^H^H^HCAM code.
