27 27 * moddir:
28 28 *
29 29 * Set the search path for modules. This has a format similar to the
30 30 * csh path variable. If the module isn't found in the first directory
31 31 * it tries the second and so on. The default is /kernel /usr/kernel
32 32 *
33 33 * Example:
34 34 * moddir: /kernel /usr/kernel /other/modules
35 35
36 36
37 37
38 38 * root device and root filesystem configuration:
39 39 *
40 40 * The following may be used to override the defaults provided by
41 41 * the boot program:
42 42 *
43 43 * rootfs: Set the filesystem type of the root.
44 44 *
45 45 * rootdev: Set the root device. This should be a fully
46 46 * expanded physical pathname. The default is the
47 47 * physical pathname of the device where the boot
48 48 * program resides. The physical pathname is
49 49 * highly platform and configuration dependent.
50 50 *
51 51 * Example:
52 52 * rootfs:ufs
53 53 * rootdev:/sbus@1,f8000000/esp@0,800000/sd@3,0:a
54 54 *
55 55 * (Swap device configuration should be specified in /etc/vfstab.)
56 56
57 57
58 58
59 59 * exclude:
60 60 *
61 61 * Modules appearing in the moddir path which are NOT to be loaded,
62 62 * even if referenced. Note that `exclude' accepts either a module name,
63 63 * or a filename which includes the directory.
64 64 *
65 65 * Examples:
66 66 * exclude: win
67 67 * exclude: sys/shmsys
68 68
69 69

71 71 * forceload:
72 72 *
73 73 * Cause these modules to be loaded at boot time, (just before mounting
74 74 * the root filesystem) rather than at first reference. Note that
75 75 * forceload expects a filename which includes the directory. Also
76 76 * note that loading a module does not necessarily imply that it will
77 77 * be installed.
78 78 *
79 79 * Example:
80 80 * forceload: drv/foo
81 81
82 82
83 83
84 84 * set:
85 85 *
86 86 * Set an integer variable in the kernel or a module to a new value.
87 87 * This facility should be used with caution. See system(4).
88 88 *
89 89 * Examples:
90 90 *
91 91 * To set variables in 'unix':
92 92 *
93 93 * set nautopush=32
94 94 * set maxusers=40
95 95 *
96 96 * To set a variable named 'debug' in the module named 'test_module'
97 97 *
98 98 * set test_module:debug = 0x13

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

150 +* cfgadm(1M)-centric model of hotpluggin' appears to be basically unnecessary.
