(I guess this is category xsrc... it might be bin or kern...)

If you kill -1 1 to get init to reread /etc/ttys, but you have an X server
running on a virtual console, then the X server loses the ability to connect
to the virtual console via ctrl-alt-fX. 


All of this assumes using wscons:

1) Start an X server via xdm's Xservers file. Give as the last argument on the
line for the local server "vt6".

2) Boot machine. Observe X started on virtual console. Realize you actually
wanted it on vt7, and realize you messed up counting from zero and
disabled the wrong tty in /etc/ttys (ttyE6 == F7 == X's vt7).

3) Fix /etc/ttys.

4) kill -1 1

5) Observe how you can't ctrl-alt-f6 or -f7 to your X server, instead getting
the text console (with our without a working login prompt, depending on
your /etc/ttys).

6) Curse (you can do this without wscons but I don't recommend it.)

(killing xdm and restarting it fixes things until the next kill -1 1)

Related bug: X will occasionally have the keyboard get weird if the 
virtual console X is on also has a getty running on it -- it looks like X
and getty fight for control.


Sorry, no quick fixes this time.
