HP-UX System Administrator's Guide: Configuration Management

Each saved configuration can also have a title. The title can be used to provide yourself
with a longer description of the configuration’s purpose or settings. It is optional.
Each saved configuration also has a pair of timestamps. The Created/createtime
stamp indicates when the configuration was created (kconfig –s). The
Modify/modifytime stamp indicates when the configuration was last changed. Each
timestamp is associated with the login name of the user who performed the action.
The kernel itself is located in a subdirectory of /stand that has the same name as the
configuration.
Associated with each saved configuration is a complete set of module state settings
and tunable value settings. These can be seen by using:
# kcmodule –c config
and
# kctune –c config
or by using
# kconfig –a config
Using and Modifying Saved Configurations
Creating Saved Configurations
Saved kernel configurations can be created in three ways: by saving the currently
running configuration, by copying an existing saved configuration, or by reading a
system file.
To save the currently running configuration, use kconfig -s (save). The resulting
saved configuration will include any changes to the currently running configuration
that are being held for next boot.
An existing saved configuration can be copied using kconfig -c (copy).
For information on working with system files, see “Managing Configurations with
System Files” (page 192).
Using Saved Configurations
A saved configuration can be loaded using kconfig -l (load). This changes the
configuration of the currently running kernel to match what was saved. If the
configuration can be changed without a reboot, the changes will take effect immediately.
Otherwise, all of the changes will be held for next boot.
Sometimes you may want to force the configuration change to be held for next boot,
instead of applying it immediately. In these cases, you can mark the saved configuration
for use at next boot using kconfig -n (next boot). HP recommends that this option
be used only when the next boot is expected to be soon. If, for example, the next boot
doesn’t happen for months after you make such a change, the system administrator
