If you have network on a USB ethernet dongle for example, you want to delay the probing until it is really used. So you could provide a script here which calls "usb; dhcp" or something like that. For a fat filesystem on a mmc card it could be "mci0.probe=1; mkdir /fat; mount /dev/disk0.1 fat /fat" > I like the idea > > but we should use the menu to manage it? I think it should always work without the menu, but of course it's nice to integrate it into the menu also.
