This is typically useful in cases where built-in 52 kernel modules are complemented by custom built versions of the 53 same and the user wishes to affect the priority of processing in 54 order to override the module version supplied by the kernel. 55 </para> 56 <para> 57 The format of files under <filename>depmod.d</filename> is simple: one 58 command per line, with blank lines and lines starting with '#' 59 ignored (useful for adding comments). A '\' at the end of a line 60 causes it to continue on the next line, which makes the files a 61 bit neater. 62 </para> 63 </refsect1> 64 <refsect1> 65 <title>COMMANDS</title> 66 <variablelist> 67 <varlistentry> 68 <term>search <replaceable>subdirectory...</replaceable> 69 </term> 70 <listitem> 71 <para> 72 This allows you to specify the order in which /lib/modules 73 (or other configured module location) subdirectories will 74 be processed by <command>depmod</command>. Directories are 75 listed in order, with the highest priority given to the 76 first listed directory and the lowest priority given to the last 77 directory listed. The special keyword <command>built-in</command> 78 refers to the standard module directories installed by the kernel. 79 Another special keyword <command>external</command> refers to the 80 list of external directories, defined by the 81 <command>external</command> command. 82 </para> 83 <para> 84 By default, depmod will give a higher priority to 85 a directory with the name <command>updates</command> 86 using this built-in search string: "updates built-in" 87 but more complex arrangements are possible and are 88 used in several popular distributions. 89 </para> 90 </listitem> 91 </varlistentry> 92 <varlistentry> 93 <term>override <replaceable>modulename</replaceable> <replaceable>kernelversion</replaceable> <replaceable>modulesubdirectory</replaceable> 94 </term> 95 <listitem> 96 <para> 97 This command allows you to override which version of a 98 specific module will be used when more than one module 99 sharing the same name is processed by the 100 <command>depmod</command> command. It is possible to 101 specify one kernel or all kernels using the * wildcard. 102 <replaceable>modulesubdirectory</replaceable> is the 103 name of the subdirectory under /lib/modules (or other 104 module location) where the target module is installed. 105 </para> 106 <para> 107 For example, it is possible to override the priority of 108 an updated test module called <command>kmod</command> by 109 specifying the following command: "override kmod * extra". 110 This will ensure that any matching module name installed 111 under the <command>extra</command> subdirectory within 112 /lib/modules (or other module location) will take priority 113 over any likenamed module already provided by the kernel. 114 </para> 115 </listitem> 116 </varlistentry> 117 <varlistentry> 118 <term>external <replaceable>kernelversion</replaceable> 119 <replaceable>absolutemodulesdirectory...</replaceable> 120 </term> 121 <listitem> 122 <para> 123 This specifies a list of directories, which will be checked 124 according to the priorities in the <command>search</command> 125 command. The order matters also, the first directory has the higher 126 priority. 127 </para> 128 <para> 129 The <replaceable>kernelversion</replaceable> is a POSIX regular 130 expression or * wildcard, like in the <command>override</command>. 131 </para> 132 </listitem> 133 </varlistentry> 134 <varlistentry> 135 <term>exclude <replaceable>excludedir</replaceable> 136 </term> 137 <listitem> 138 <para> 139 This specifies the trailing directories that will be excluded 140 during the search for kernel modules. 141 </para> 142 <para> 143 The <replaceable>excludedir</replaceable> is the trailing directory 144 to exclude 145 </para> 146 </listitem> 147 </varlistentry> 148 </variablelist> 149 </refsect1> 150 151 <refsect1><title>COPYRIGHT</title> 152 <para> 153 This manual page Copyright 2006-2010, Jon Masters, Red Hat, Inc. 154 </para> 155 </refsect1> 156 <refsect1><title>SEE ALSO</title> 157 <para> 158 <citerefentry> 159 <refentrytitle>depmod</refentrytitle><manvolnum>8</manvolnum> 160 </citerefentry> 161 </para> 162 </refsect1> 163</refentry> 164
