stune -- local system settings for tunable parameters

Synopsis

   stune
   stune.current

Description

One of the Installable Driver/Tunable Paramers kernel configuration files, the /etc/conf/cf.d/stune file, contains tunable parameters for the kernel modules to be configured into the next system to be built (see idbuild(ADM)). The parameter settings in the stune file are used to override the default values specified in the mtune file.

The contents of the stune file will only affect the next kernel rebuild. Once the new kernel has been installed to /stand and booted, the stune file is copied to stune.current. Any change made to the stune.current file using the idtune(ADM) command with the -c option will affect all the loadable kernel modules subsequently configured into the running system.

Package scripts should never access /etc/conf/cf.d/stune or /etc/conf/cf.d/stune.current files directly; only the idtune(ADM) command should be used.

The stune and stune.current files contain one line for each parameter to be set. Each line contains two positional fields separated by white space:

   	parameter-name new-value

Blank lines and lines beginning with ``#'' or ``*'' are considered comments and are ignored.

The stune and stune.current fields are:


parameter-name
Specifies the name of the tunable parameter, as defined in the Mtune file.

new-value
Specifies the new value to be used to override the default value specified for this tunable parameter in the Mtune file. This value must fall within the valid range of values specified for this parameter in the Mtune file.

For detailed information on the system tunable parameters, see ``Tunable parameters'' in Monitoring and tuning the system.
