setoncenv(1M)

Add a supported configuration variable, or change the value of an existing configuration variable in the configuration file. The -a option cannot be used to set a kernel tunable variable. You must use kctune to manage kernel tunable variables.

Display the values of all configuration variables and kernel tunable variables supported by setoncenv. Optionally you can specify either a subsystem or an individual variable.

Remove or comment out a configuration variable in a configuration file. The setoncenv command will not remove or comment out variables from /etc/rc.config.d/nfsconf or /etc/rc.config.d/namesvrs; it also cannot be used to remove kernel tunable variables. The value parameter is only used when removing an entry for a configuration variable that supports multiple entries in a configuration file (for example, AUTOMOUNTD_ENV).

Provide verbose output.

Will display all variables associated with the AutoFS subsystem.

Will display all variables associated with the KEY, keyserv subsystem.

Will display all variables associated with the Kernel Lock Manager subsystem.

Will display all variables associated with the kernel RPC subsystem.
