HP-UX System Administrator's Guide: Configuration Management

# kconfig –e filename
• Export a saved configuration:
# kconfig –e configname filename
NOTE: /stand/system, and any system file created by exporting the running
configuration, always reflects any changes that are being held for next boot.
Once you have a system file, you can edit it using any text editor, making the changes
you desire. After editing it, you can apply the changes with the kconfig -i (import)
command. This command has three forms:
• Import to running configuration now:
kconfig -i filename
• Import and hold for next boot:
kconfig -h -i filename
• Import to saved configuration:
kconfig -i configname filename
In the first form, if the changes cannot be applied to the running system, they will be
held for next boot.
For backward compatibility, the mk_kernel command is still available to apply changes
made in a system file. Note, however, that its name is no longer accurate since it will
apply configuration changes without making a kernel if it can. This command has the
form:
mk_kernel [-o target] [-s filename]
filename is the name of the system file to read; if not specified, /stand/system is
used. To import to a saved configuration, target should be the name of the
configuration. To import to the currently running system, taking effect immediately if
possible, target should be /stand/vmunix. (Changes will be held until next boot
if they cannot be applied immediately.) If target is omitted, the changes will be made
to a saved configuration called hpux_test. It is not possible to import to the currently
running system, forcing changes to be held for next boot, using mk_kernel. Use
kconfig -h -i for that purpose.
It is important to note that the system files at /stand/system and
/stand/configname/system are automatically recreated after every configuration
change. In this process, comments in the system file are not preserved. Also, the ordering
of lines in the file is not preserved. Therefore, HP recommends against putting comments
in the system files. Instead, use the -C (comment) option when importing the
configuration, to add your comments directly to the kernel configuration log file. (See
“The Kernel Configuration Log File” (page 195).)
