r315733 (imp): Impelemnt ttys onifexists in init. Implement a new init(8) option in /etc/ttys. If this option is present on the entry in /etc/ttys, the entry will be active if and only if it exists. If the name starts with a '/', it will be considered an absolute path. If not, it will be a path relative to /dev. This allows one to turn off video console getty that aren't present (while running a getty on them even when they aren't the system console). Likewise with serial ports. It differs from onifconsole in only requiring the device exist rather than it be listed as one of the system consoles. r315737 (ngie): Unbreak world by adding sys/stat.h for stat(2) r315740 (imp): Simplify the code a little. r330054 (trasz): Improve missing tty handling in init(8). This removes a check that did nothing - it was checking for ENXIO, which, with devfs, is no longer returned - and was badly placed anyway, and replaces it with similar one that works, and is done just before starting getty, instead of being done when rereading ttys(5). From the practical point of view, this makes init(8) handle disappearing terminals (eg /dev/ttyU*) gracefully, without unneccessary getty restarts and resulting error messages.
