Yes, it would simply work :)
Redirecting stdin and stdout is done for the benefit of the ioctl(2)
interface that vidcontrol(8) uses, so it can actually modify the settings
of the tty in question (in this loop, all virtual consoles).
Since the '-m on' only notes that the cursor should be shown when needed,
not always, IMHO it would be a good solution. It would do no harm -
the mouse cursor is only drawn on mouse movement, and hidden on a keypress -
so there would be no mouse cursor when the mouse is not attached.
When the mouse is attached, the persistent 'mouse cursor on' state would
make sure that the cursor is displayed.
Again, this is just my opinion, YMMV.
G'luck,
Peter
