Internal Program Version: blog  2.28

The blogd daemon determines the real underlying character device of
/dev/console. Blogd spawns a pty/tty pair to reconnect the current
/dev/console with the slave of the pty/tty pair. During writing
information from this slave to the real character device a ring
buffer is used to hold the information for writing it to an existing
logging file.
