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
              logfile~ 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
       configuration.)   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.
