| On ChromeOS, brltty is run as its own user instead of root. |
| It has group memberships to allow it access to the tty. |
| This patch changes an open call so that /dev/tty0 is only opened for |
| writing (it just issues some ioctl calls on the device), which is necessary |
| because the tty group only has write access to /dev/tty0. |
