NAME
       bootlog - write stdout/stderr of a program to file

SYNOPSIS
       bootlog [-12ctar] logsize logfile program [arguments]


DESCRIPTION
       bootlog	is  used  to start a program and write stdout/stderr to a disk
       file.  This works also before mouning any file systems.

       bottlog is designed to log the output of scripts/services at boot time,
       before mounting any file system.	 This is typical for system init.

       bootlog expects that when the program exits, the logfile is writable!


OPTIONS
       -1     log only stdout

       -2     log only stderr;	default is to log stdout and stderr

       -c     create logfile

       -t     truncate logfile

       -a     append to logfile

       -r     replace old logfile with logfile~

       logsize
	      maximal size of output to be logged

       logfile
	      disk file name

       program
	      the name of the program to start

       arguments
	      additional arguments for program


WARNING
       Use the option -c to force creating of the logfile.

       Actually the options -c, -a, -t add O_CREAT, O_APPEND, O_TRUNC flags to
       open(2) for logfile


EXAMPLE
       bootlog -ctr 120000 /tmp/.sysinit.log /etc/rc.d/rc.sysinit

       You will have the files /tmp/.sysinit.log and /tmp/.sysinit.log~
