I've been thinking about this "change disk now" questions that the kernel might need to ask.
I thought I'd make a character device that simply outputs the question to be posed to the user.
On a text console you just run something similar to
cat /dev/changemessages &
On an X display a small tool would present in a requestor anything that could come up.
There might need to be some feedback saying "OK. Done".
