.TH BOOTLOGD 8 "Jul 21, 2003" "" "Linux System Administrator's Manual"
.SH NAME
bootlogd \- record boot messages
.SH SYNOPSIS
.B /sbin/bootlogd
.RB [ \-d ]
.RB [ \-r ]
.RB [ \-v ]
.RB [ " -l logfile " ]
.RB [ " -p pidfile " ]
.SH DESCRIPTION
\fBBootlogd\fP runs in the background and copies all strings sent to the
\fI/dev/console\fP device to a logfile. If the logfile is not accessible,
the messages will be buffered in-memory until it is.
.SH OPTIONS
.IP \fB\-d\fP
Do not fork and run in the background.
.IP \fB\-r\fP
If there is an existing logfile called \fIlogfile\fP rename it to
\fIlogfile~\fP unless \fIlogfile~\fP already exists.
.IP \fB\-v\fP
Show version.
.IP \fB\-l logfile\fP
Log to this logfile. The default is \fI/var/log/boot\fP.
.IP \fB\-p pidfile\fP
Put process-id in this file. The default is no pidfile.
.SH BUGS
Bootlogd works by redirecting the console output from the console
device. It copies that output to the real console device and a
logfile. There is no standard way to find out the real console device
if you have a new-style \fI/dev/console\fP device (major 5, minor 1).
\fBBootlogd\fP tries to parse the kernel command line, looking for
console= lines and deducts the real console device from that. If that
syntax is ever changed by the kernel, or a console-type is used
bootlogd does not know about, bootlogd will not work.
