autoconfig(1M)autoconfig(1M)NAMEautoconfig - configure kernel
SYNOPSIS
/etc/autoconfig [-vnf] [-p toolroot] [-d /var/sysgen]
[-o lbootopts] [start|stop]
DESCRIPTION
The autoconfig command is used invoke lboot and other commands to
generate a UNIX kernel. The autoconfig command is also a startup script
in /etc/init.d.
The options are as:
-v Requests verbose output from lboot and other commands.
-f Generates a new kernel even if it appears that no hardware or
software changes have been made. Use of -f will clear any
options set in the /var/config/autoconfig.options file.
-p toolroot
Specifies the directory tree containing the compiler and other
tools needed to generate the kernel.
-d /var/sysgen
Specifies the directory tree containing the system configuration
modules and binaries.
-n Performs a dry run of lboot and reports if a new kernel would be
created. If -f is also given, it overrides this option.
start Used by rc2 when the system is starting.
stop Used by rc0 when the system is stopping.
The autoconfig command also uses the /var/config/autoconfig.options file
to tell lboot to configure a new kernel automatically or to prompt for
permission before configuring a new kernel. The
/var/config/autoconfig.options file contains a -T by default, which
indicates to lboot to configure the kernel automatically if necessary.
This option can be changed to a -t to force lboot to prompt for
permission before configuring a new kernel.
Warning: Any new kernel that was generated by a previous invocation of
autoconfig will be removed, even if the -n option is used.
ENVIRONMENT VARIABLES
In addition to the environment variables used by lboot, autoconfig itself
uses some environment variables. If you have these variables set for
some other purpose, you may need to unset them before running autoconfig.

NOTE: This means that they should not be set in the global shell startup
files in /etc.
UNIX The file to check to see if it is out of date (defaults to
/unix) and also what the basename of the newly built kernel
will be, if necessary.
SYSGEN Passed as the base directory for the kernel files (see also
WORKDIR below) and as the base directory name for the
arguments below, if they are not set in the environment.
BOOTAREA Passed as the -b argument to lboot.
SYSTEM Passed as the -s argument to lboot.
MASTERD Passed as the -m argument to lboot.
STUNEFILE Passed as the -c argument to lboot.
MTUNEDIR Passed as the -n argument to lboot.
WORKDIR Passed as the -w argument to lboot.
