* SYSTEM SPECIFICATION FILE
*

*
* !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
*
* It is not recommended to edit this file directly but rather
* to deliver configuration fragments into files under /etc/system.d;
* files in /etc/system.d are combined in alphabetical order and read by
* the kernel before this file (/etc/system) is processed.
*
* Refer to the system(5) manual page for more information and
* recommendations on naming fragment files.
*
* !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
*
* As SmartOS ships with /etc/ off a ramdisk, we don't support using the
* /etc/system.d mechanism.
*

* moddir:
*
*	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(5).
*
*	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

*
* The traditional (and essentially entirely brain dead) cfgadm(1M)-centric
* model of hotpluggin' appears to be basically unnecessary.  This tunable
* enables the system to create device nodes for newly inserted devices
* automatically.  See: usr/src/uts/common/io/sata/impl/sata.c:97
*
set sata:sata_auto_online=1

*
* We want to limit the time spent in any one I/O to 10 seconds for targets
* that are not optical.  This is still a very long time; our queue depth is
* typically 10 or less, and disks will usually fail a command after 2-3s.
* So we'd have to have multiple reads of bad sectors queued up to have any
* chance of timing out.  In practice, timeouts occur because of problems with
* disk controllers or firmware, not media errors, and in those cases it will
* not help at all to wait longer.
