Fair enough. Thanks.
Another scenario may be where (say) a network driver is modprobed
from a hotpluggable disk controller. You want to be able to load
the netdriver, pop out the disk controller and then insert the network
card. Or vice-versa - load a parallel port driver across NFS then
pull the network card and push the parallel port card. Could use
local disks for this, of course.
