*ident        \"@(#)system        1.18        97/06/27 SMI\" /* SVR4 1.5 */\r\n*\r\n* SYSTEM SPECIFICATION FILE\r\n*\r\n\r\n* moddir:\r\n*\r\n*        Set the search path for modules.  This has a format similar to the\r\n*        csh path variable. If the module isn\'t found in the first directory\r\n*        it tries the second and so on. The default is /kernel /usr/kernel\r\n*\r\n*        Example:\r\n*                moddir: /kernel /usr/kernel /other/modules\r\n   通過使用moddir: 搜索模塊目錄列表，可以修改默認(rèn)的路經(jīng)\r\n\r\n\r\n* root device and root filesystem configuration:\r\n*\r\n*        The following may be used to override the defaults provided by\r\n*        the boot program:\r\n*\r\n*        rootfs:                Set the filesystem type of the root.\r\n*        用來標(biāo)志根文件系統(tǒng)類型\r\n*        rootdev:        Set the root device.  This should be a fully\r\n*                        expanded physical pathname.  The default is the\r\n*                        physical pathname of the device where the boot\r\n*                        program resides.  The physical pathname is\r\n*                        highly platform and configuration dependent.\r\n*         用來標(biāo)示根設(shè)備和引導(dǎo)程序駐留的設(shè)備不同（指定根設(shè)備）\r\n*        Example:\r\n*                rootfs:ufs\r\n*                rootdev:/sbus@1,f8000000/esp@0,800000/sd@3,0:a\r\n*\r\n*        (Swap device configuration should be specified in /etc/vfstab.)\r\n\r\n\r\n\r\n* exclude:\r\n*\r\n*        Modules appearing in the moddir path which are NOT to be loaded,\r\n*        even if referenced. Note that `exclude\' accepts either a module name,\r\n*        or a filename which includes the directory.\r\n*\r\n*        Examples:\r\n*                exclude: win\r\n*                exclude: sys/shmsys\r\n        不再使用的模塊通過exclude: 來排除\r\n\r\n\r\n* forceload:\r\n*\r\n*        Cause these modules to be loaded at boot time, (just before mounting\r\n*        the root filesystem) rather than at first reference. Note that\r\n*         forceload expects a filename which includes the directory. Also\r\n*        note that loading a module does not necessarily imply that it will\r\n*        be installed.\r\n*\r\n*        Example:\r\n*                forceload: drv/foo\r\n        使用forceload: 需要在初始化時強(qiáng)制加載的模塊\r\n\r\n\r\n* set:\r\n*\r\n*        Set an integer variable in the kernel or a module to a new value.\r\n*        This facility should be used with caution.  See system(4).\r\n*\r\n*        Examples:\r\n*\r\n*        To set variables in \'unix\':\r\n*\r\n*                set nautopush=32\r\n*                set maxusers=40\r\n*\r\n*        To set a variable named \'debug\' in the module named \'test_module\'\r\n*\r\n*                set test_module:debug = 0x13
