This option never made much sense. It was originally intended to make sure that the usual startup output of sysv scripts goes to the terminal. However, since SysV scripts started from a terminal would not output to that terminal, but rather /dev/console this effect was more often than not actually taking place. Nowadays systemd has much nicer boot time status output than SysV which makes the sysv output redundant. Finally, all output of services goes to the journal anyway, and is not lost. Hence, let's drop this option, and simplify things a bit.

hardware watchdog device to be

present, as it is commonly the case in

embedded and server systems. Not all

out. By default

defaults to 0 (off), and
