Currently tap(4) device gets to 'down' state when the last process closes it, regardless of the original 'up/down' state. Will it be reasonable to modify this behavior and keep this bit 'was_up_before_open', and leave it 'up' if it was 'up' when it was first opened? Practically speaking, I set it up in rc.conf to be 'up' with the particular IP, but it goes to 'down' state when VirtualBox closes it. If tap(4) can be 'up' without users, there shouldn't be any problem in leaving it 'up' after use as well? Yuri
