*Set the search path for modules. This has a format
*similar to the csh path variable. If the module isn't
*found in the first directory it tries the second and
*so on. The default is /kernel /usr/kernel
*
*Example:
*moddir: /kernel /usr/kernel /other/modules
* root device and root filesystem configuration:
*
*The following may be used to override the defaults
*provided by the boot program:
*
*rootfs: Set the filesystem type of the root.
*
*rootdev: Set the root device. This should be a fully
* expanded physical pathname. The default is the
* physical pathname of the device where the boot
* program resides. The physical pathname is
* highly platform and configuration dependent.
*
*Example:
* rootfs:ufs
* rootdev:/sbus@1,f8000000/esp@0,800000/sd@3,0:a
*
*(Swap device configuration should be specified in
*/etc/vfstab.)
* exclude:
*
*Modules appearing in the moddir path which are NOT to be
*loaded, even if referenced. Note that ?exclude' accepts
*either a module name, or a filename which includes the
*directory.
*
*Examples:
* exclude: win
* exclude: sys/shmsys
* forceload:
*
*Cause these modules to be loaded at boot time, (just
*before mounting the root filesystem) rather than at
*first reference. Note that forceload expects a filename
*which includes the directory. Also note that loading a
*module does not necessarily imply that it will be
*installed.
*
*Example:
* forceload: drv/foo
* set:
*
*Set an integer variable in the kernel or a module to
*a new value.
*This facility should be used with caution.
*See system(4).
*
*Examples:
*
*To set variables in 'unix':
*
* set nautopush=32
* set maxusers=40
*
*To set a variable named 'debug' in the module named
*'test_module'
*
* set test_module:debug = 0x13
