doconfig

doconfig(8)						      System Manager's Manual						       doconfig(8)

Name
       doconfig - a program to aid system configuration

Syntax
       /etc/doconfig [-c config_file] [-e ed_script]

Description
       The  shell  script modifies a copy of the GENERIC configuration file for a new ULTRIX system kernel.  The script prompts you for the system
       name.  If the system name does not currently exist, a system configuration file with that system name is built.

       Whether the configuration file is built or not, the script then allows you to edit, configure, and build until both the	configuration  and
       the kernel build run without errors.  Additional runs of can be made to tune the configuration further.

       When new hardware is added to a system, the configuration file should be updated to reflect the new system configuration.  When updating an
       existing configuration file or creating a new configuration file with the system must be operating the generic kernel or new  hardware  may
       not be found.  To successfully complete the process, follow these steps:

       1.   Save the running as

       2.   Move to

       3.   Reboot the system to single user mode.

       4.   Check file systems.

       5.   Mount the file system.

       6.   Run the program.  (When execution is complete, make a note of the message prints showing the path and location of the new

       7.   Move to

       8.   Copy the new (from the message noted above) to

       9.   Reboot the system.

Options
       -c     The  name  of  the  existing  configuration  file should be supplied without specifying the pathname.  This file should exist in the
	      directory.  A new kernel is built using the specified configuration file.

       -e     When specified, the configuration file is edited by the ed script before building the new kernel.
