In which world did you live the last months ;) ? Sorry, I couldn't
insist. 

Our VDR-Distribution yaVDR is optimized for a short boot. With old
fashioned PCI cards you can get down to 6 seconds boot time since grub,
but if one of our user decides to buy another p. e. usb device, we
have to delay the boot up to 30 seconds to allow the usb device to get
ready. With device hotplugging there would be no need to wait for this
device and the user would already see tv 30 seconds earlier. Believe me
there are users that thinks this matters.
