It wasn't and still isn't. A TTY device is a character device and a disk driver a block device. And if it is the same then why give that error message/warning? I'm probably grossly oversimplifying things but I'm using my unix systems to do work for me.

Still, is not fsdb intended for or primarily used in single user mode. I.e. with most fs's unmounted? > I suppose you could argue that; if you want to, send-pr is your > friend.
