BOOTLOGD(8)	      Linux System Administrator's Manual	   BOOTLOGD(8)

NAME
       bootlogd - record boot messages

SYNOPSIS
       /sbin/bootlogd [-c] [-d] [-r] [-s] [-v] [ -l logfile ] [ -p pidfile ]

DESCRIPTION
       Bootlogd	 runs  in  the	background  and copies all strings sent to the
       /dev/console device to a logfile. If the logfile is not accessible, the
       messages will be kept in memory until it is.

OPTIONS
       -d     Do not fork and run in the background.

       -c     Attempt  to  write to the logfile even if it does not yet exist.
	      Without this option, bootlogd  will  wait	 for  the  logfile  to
	      appear before attempting to write to it.	This behavior prevents
	      bootlogd from creating logfiles under mount points.

       -r     If there is an existing logfile called logfile rename it to log‐
	      file~ unless logfile~ already exists.

       -s     Ensure  that  the data is written to the file after each line by
	      calling fdatasync(3).  This will slow  down  a  fsck(8)  process
	      running in parallel.

       -v     Show version.

       -l logfile
	      Log to this logfile. The default is /var/log/boot.

       -p pidfile
	      Put process-id in this file. The default is no pidfile.

BUGS
       Bootlogd	 works	by  redirecting	 the  console  output from the console
       device.	(Consequently bootlogd requires PTY support in the kernel con‐
       figuration.)  It copies that output to the real console device and to a
       log file.  There is no standard way of ascertaining  the	 real  console
       device  if  you have a new-style /dev/console device (major 5, minor 1)
       so bootlogd parses the kernel  command  line  looking  for  console=...
       lines and deduces the real console device from that.  If that syntax is
       ever changed by the kernel, or a console type  is  used	that  bootlogd
       does not know about then bootlogd will not work.
