Hmm, I am trying to remember what halted behaves like. I would not
expect it to clear the terminals, although I would expect them to not
really do anything useful anymore since the getty that was running on
them is gone. I tend to use 'poweroff' personally so that it actually
turns off when done shutting down. Shutting down but staying on doesn't
seem very useful to me. control+alt+delete not working does seem odd,
unless it is a usb keyboard, in which case it is expected I think since
the bios emulates the keyboard interface for usb, until the kernel boots
and takes over by disabling the emulation, and I doubt it reenables it
at halt, so a usb keyboard would be dead for the most part at that point
(although you said you could switch terminals). Perhaps there simply
isn't a control+alt+delete handler left at that point.
