  27 * moddir:
  28 *
  29 *       Set the search path for modules.  This has a format similar to the
  30 *       csh path variable. If the module isn't found in the first directory
  31 *       it tries the second and so on. The default is /kernel /usr/kernel
  32 *
  33 *       Example:
  34 *               moddir: /kernel /usr/kernel /other/modules
  35 
  36 
  37 
  38 * root device and root filesystem configuration:
  39 *
  40 *       The following may be used to override the defaults provided by
  41 *       the boot program:
  42 *
  43 *       rootfs:         Set the filesystem type of the root.
  44 *
  45 *       rootdev:        Set the root device.  This should be a fully
  46 *                       expanded physical pathname.  The default is the
  47 *                       physical pathname of the device where the boot
  48 *                       program resides.  The physical pathname is
  49 *                       highly platform and configuration dependent.
  50 *
  51 *       Example:
  52 *               rootfs:ufs
  53 *               rootdev:/sbus@1,f8000000/esp@0,800000/sd@3,0:a
  54 *
  55 *       (Swap device configuration should be specified in /etc/vfstab.)
  56 
  57 
  58 
  59 * exclude:
  60 *
  61 *       Modules appearing in the moddir path which are NOT to be loaded,
  62 *       even if referenced. Note that `exclude' accepts either a module name,
  63 *       or a filename which includes the directory.
  64 *
  65 *       Examples:
  66 *               exclude: win
  67 *               exclude: sys/shmsys
  68 
  69 
  70 
  71 * forceload:
  72 *
  73 *       Cause these modules to be loaded at boot time, (just before mounting
  74 *       the root filesystem) rather than at first reference. Note that
  75 *       forceload expects a filename which includes the directory. Also
  76 *       note that loading a module does not necessarily imply that it will
  77 *       be installed.
  78 *
  79 *       Example:
  80 *               forceload: drv/foo
  81 
  82 
  83 
  84 * set:
  85 *
  86 *       Set an integer variable in the kernel or a module to a new value.
  87 *       This facility should be used with caution.  See system(4).
  88 *
  89 *       Examples:
  90 *
  91 *       To set variables in 'unix':
  92 *
  93 *               set nautopush=32
  94 *               set maxusers=40
  95 *
  96 *       To set a variable named 'debug' in the module named 'test_module'
  97 *
  98 *               set test_module:debug = 0x13

 141 * With lots of zones, each with a large limit on lwps, we need more pids.  We
 142 * could go to 999999, but for now stick with 5 digits to match the existing
 143 * default of 30000.  This is mostly being conservative, so we can bump higher
 144 * if necessary.

 152 * devices automatically.  See: usr/src/uts/common/io/sata/impl/sata.c:97
