If libfuse is available then kmscon is built with a new session type: cdev This session creates a fake TTY char-dev via CUSE (which itself uses FUSE) which then can be used by user-space as if it were a real VT. This is still incomplete and does only support basic I/O, yet. But it shows in what direction this is going. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com>
