282b987d42SAlexander Eremin* It is not recommended to edit this file directly but rather
292b987d42SAlexander Eremin* to deliver configuration fragments into files under /etc/system.d;
302b987d42SAlexander Eremin* files in /etc/system.d are combined in alphabetical order and read by
312b987d42SAlexander Eremin* the kernel before this file (/etc/system) is processed.

387c478bd9Sstevel@tonic-gate* moddir:
397c478bd9Sstevel@tonic-gate*
407c478bd9Sstevel@tonic-gate*	Set the search path for modules.  This has a format similar to the
417c478bd9Sstevel@tonic-gate*	csh path variable. If the module isn't found in the first directory
427c478bd9Sstevel@tonic-gate*	it tries the second and so on. The default is /kernel /usr/kernel
437c478bd9Sstevel@tonic-gate*
447c478bd9Sstevel@tonic-gate*	Example:
457c478bd9Sstevel@tonic-gate*		moddir: /kernel /usr/kernel /other/modules
467c478bd9Sstevel@tonic-gate
477c478bd9Sstevel@tonic-gate
487c478bd9Sstevel@tonic-gate
497c478bd9Sstevel@tonic-gate* root device and root filesystem configuration:
507c478bd9Sstevel@tonic-gate*
517c478bd9Sstevel@tonic-gate*	The following may be used to override the defaults provided by
527c478bd9Sstevel@tonic-gate*	the boot program:
537c478bd9Sstevel@tonic-gate*
547c478bd9Sstevel@tonic-gate*	rootfs:		Set the filesystem type of the root.
557c478bd9Sstevel@tonic-gate*
567c478bd9Sstevel@tonic-gate*	rootdev:	Set the root device.  This should be a fully
577c478bd9Sstevel@tonic-gate*			expanded physical pathname.  The default is the
587c478bd9Sstevel@tonic-gate*			physical pathname of the device where the boot
597c478bd9Sstevel@tonic-gate*			program resides.  The physical pathname is
607c478bd9Sstevel@tonic-gate*			highly platform and configuration dependent.
617c478bd9Sstevel@tonic-gate*
627c478bd9Sstevel@tonic-gate*	Example:
637c478bd9Sstevel@tonic-gate*		rootfs:ufs
647c478bd9Sstevel@tonic-gate*		rootdev:/sbus@1,f8000000/esp@0,800000/sd@3,0:a
657c478bd9Sstevel@tonic-gate*
667c478bd9Sstevel@tonic-gate*	(Swap device configuration should be specified in /etc/vfstab.)

687c478bd9Sstevel@tonic-gate
697c478bd9Sstevel@tonic-gate
707c478bd9Sstevel@tonic-gate* exclude:
717c478bd9Sstevel@tonic-gate*
727c478bd9Sstevel@tonic-gate*	Modules appearing in the moddir path which are NOT to be loaded,
737c478bd9Sstevel@tonic-gate*	even if referenced. Note that `exclude' accepts either a module name,
747c478bd9Sstevel@tonic-gate*	or a filename which includes the directory.
757c478bd9Sstevel@tonic-gate*
767c478bd9Sstevel@tonic-gate*	Examples:
777c478bd9Sstevel@tonic-gate*		exclude: win
787c478bd9Sstevel@tonic-gate*		exclude: sys/shmsys
797c478bd9Sstevel@tonic-gate
807c478bd9Sstevel@tonic-gate
817c478bd9Sstevel@tonic-gate
827c478bd9Sstevel@tonic-gate* forceload:
837c478bd9Sstevel@tonic-gate*
847c478bd9Sstevel@tonic-gate*	Cause these modules to be loaded at boot time, (just before mounting
857c478bd9Sstevel@tonic-gate*	the root filesystem) rather than at first reference. Note that
862b987d42SAlexander Eremin*	forceload expects a filename which includes the directory. Also
877c478bd9Sstevel@tonic-gate*	note that loading a module does not necessarily imply that it will
887c478bd9Sstevel@tonic-gate*	be installed.
897c478bd9Sstevel@tonic-gate*
907c478bd9Sstevel@tonic-gate*	Example:
917c478bd9Sstevel@tonic-gate*		forceload: drv/foo
927c478bd9Sstevel@tonic-gate
937c478bd9Sstevel@tonic-gate
947c478bd9Sstevel@tonic-gate
957c478bd9Sstevel@tonic-gate* set:
967c478bd9Sstevel@tonic-gate*
977c478bd9Sstevel@tonic-gate*	Set an integer variable in the kernel or a module to a new value.
98*bbf21555SRichard Lowe*	This facility should be used with caution.  See system(5).
997c478bd9Sstevel@tonic-gate*
1007c478bd9Sstevel@tonic-gate*	Examples:
1017c478bd9Sstevel@tonic-gate*
1027c478bd9Sstevel@tonic-gate*	To set variables in 'unix':
1037c478bd9Sstevel@tonic-gate*
1047c478bd9Sstevel@tonic-gate*		set nautopush=32
1057c478bd9Sstevel@tonic-gate*		set maxusers=40
1067c478bd9Sstevel@tonic-gate*
1077c478bd9Sstevel@tonic-gate*	To set a variable named 'debug' in the module named 'test_module'
1087c478bd9Sstevel@tonic-gate*
1097c478bd9Sstevel@tonic-gate*		set test_module:debug = 0x13
