That descriptor is then closed because it is never accessed by syslogd again; ttymsg() will reopen the tty/console under a new descriptor when needed. If the user attempts to log to a tty that is inactive outside of syslogd, then syslogd must keep that descriptor open so the tty remains accessible. For example, logging to `/dev/ttyvb` requires the initial `/dev/ttyvb` descriptor to stay open so the user can view its buffer at any time via CTRL+ALT+F12. As a result, console and tty descriptors must remain open until a potential configuration reload or a system shutdown. The given descriptor will be closed in close_filed() in such circumstances.
