setconsole: open console for writing rather than reading
The console passed to TIOCCONS has to be writable, otherwise future console writes will fail. This presumably used to work, but in current kernels (see drivers/tty/tty_io.c:redirected_tty_write) console writes are sent to vfs_write(device), which checks if the device is writable. A quick look in the linux git history doesn't show any recent changes to either tty_io or vfs_write.
