  27 *
  28 * It is not recommended to edit this file directly but rather
  29 * to deliver configuration fragments into files under /etc/system.d;
  30 * files in /etc/system.d are combined in alphabetical order and read by
  31 * the kernel before this file (/etc/system) is processed.
  32 *
  33 * Refer to the system(4) manual page for more information and
  34 * recommendations on naming fragment files.

  38 * moddir:
  39 *
  40 *       Set the search path for modules.  This has a format similar to the
  41 *       csh path variable. If the module isn't found in the first directory
  42 *       it tries the second and so on. The default is /kernel /usr/kernel
  43 *
  44 *       Example:
  45 *               moddir: /kernel /usr/kernel /other/modules
  46 
  47 
  48 
  49 * root device and root filesystem configuration:
  50 *
  51 *       The following may be used to override the defaults provided by
  52 *       the boot program:
  53 *
  54 *       rootfs:         Set the filesystem type of the root.
  55 *
  56 *       rootdev:        Set the root device.  This should be a fully
  57 *                       expanded physical pathname.  The default is the
  58 *                       physical pathname of the device where the boot
  59 *                       program resides.  The physical pathname is
  60 *                       highly platform and configuration dependent.
  61 *
  62 *       Example:
  63 *               rootfs:ufs
  64 *               rootdev:/sbus@1,f8000000/esp@0,800000/sd@3,0:a
  65 *
  66 *       (Swap device configuration should be specified in /etc/vfstab.)
  67 
  68 
  69 
  70 * exclude:
  71 *
  72 *       Modules appearing in the moddir path which are NOT to be loaded,
  73 *       even if referenced. Note that `exclude' accepts either a module name,
  74 *       or a filename which includes the directory.
  75 *
  76 *       Examples:
  77 *               exclude: win
  78 *               exclude: sys/shmsys
  79 
  80 
  81 
  82 * forceload:
  83 *
  84 *       Cause these modules to be loaded at boot time, (just before mounting
  85 *       the root filesystem) rather than at first reference. Note that
  86 *       forceload expects a filename which includes the directory. Also
  87 *       note that loading a module does not necessarily imply that it will
  88 *       be installed.
  89 *
  90 *       Example:
  91 *               forceload: drv/foo
  92 
  93 
  94 
  95 * set:
  96 *
  97 *       Set an integer variable in the kernel or a module to a new value.
  98 *       This facility should be used with caution.  See system(4).
  99 *
 100 *       Examples:
 101 *
 102 *       To set variables in 'unix':
 103 *
 104 *               set nautopush=32
 105 *               set maxusers=40
 106 *
 107 *       To set a variable named 'debug' in the module named 'test_module'
 108 *
 109 *               set test_module:debug = 0x13
