Hi Mak,

How do you launch the ./open_test? Please provide me a complete instructions: boot, log in, etc... Also note that there 
is no controlling terminal until tinit started.

> # ./open_test /dev/tty
> Opening '/dev/monkeys'
> Failed: No such file or directory

Are you sure?

Respectfully,
Oleg
