/dev/tty* and sysfs nodes don't track permissions, owner with each other,
so you are providing interfaces that either expose information they
shouldn't (which screen is valuable info in some environments), or don't
expose info they should.

sysfs also lacks vhangup so you can't fix it right now either.

Start by explaining why the current interface doesn't work for you, but
