Yes. It's very unclear unless you do mind reading, but I had in mind mounted filesystems
such as /home on a USB stick or firewire Reasonable? yes! But such devices have to
be rediscovered and allocated in such a way that the user can resume using the device
as soon as it has been found. And it should not fail miserably if the user forgets to connect
the device before resuming the machine. As you cannot unmount /home (usually) the
kernel must remember the device somehow or make mounting file systems more loosely
than today.
