You tell the user they're an idiot. You sould not be changing the ID of
live devices.

One thing to note here is that the recomended practice (which I'll admit I
ignore) is to wire down your known devices. So for instance sd2 will
always be target 4 on scsibus 0, regardles of what's turned on or off.

I agree that we have a ways to go on being able to remove devices, but I
think we will be able to require a certain amount of user savvy to make it
work.

Take care,
