[he gazes > wistfully off into the distance :-)] I have a cloning pty driver and cloning bfs and tun and vnode drivers as well. It requires some semantic changes to the devfs that PHK and Julian have opposed, so far. Specifically, I have to be able to open a directory and treat it as a device, and then I need clone ioctl()'s (this is a better approach than using an alternate vp passback, as someone suggested). It also requires switching over to devfs, which you have opposed, so, far. So, when we switching -current to solely devfs? 8-).
