This is typically useful in cases where built-in 51 kernel modules are complemented by custom built versions of the 52 same and the user wishes to affect the priority of processing in 53 order to override the module version supplied by the kernel. 54 </para> 55 <para> 56 The format of files under <filename>depmod.d</filename> is simple: one 57 command per line, with blank lines and lines starting with '#' 58 ignored (useful for adding comments). A '\' at the end of a line 59 causes it to continue on the next line, which makes the files a 60 bit neater. 61 </para> 62 </refsect1> 63 <refsect1> 64 <title>COMMANDS</title> 65 <variablelist> 66 <varlistentry> 67 <term>search <replaceable>subdirectory...</replaceable> 68 </term> 69 <listitem> 70 <para> 71 This allows you to specify the order in which /lib/modules 72 (or other configured module location) subdirectories will 73 be processed by <command>depmod</command>. Directories are 74 listed in order, with the highest priority given to the 75 first listed directory and the lowest priority given to the last 76 directory listed. The special keyword <command>built-in</command> 77 refers to the standard module directories installed by the kernel. 78 </para> 79 <para> 80 By default, depmod will give a higher priority to 81 a directory with the name <command>updates</command> 82 using this built-in search string: "updates built-in" 83 but more complex arrangements are possible and are 84 used in several popular distributions. 85 </para> 86 </listitem> 87 </varlistentry> 88 <varlistentry> 89 <term>override <replaceable>modulename</replaceable> <replaceable>kernelversion</replaceable> <replaceable>modulesubdirectory</replaceable> 90 </term> 91 <listitem> 92 <para> 93 This command allows you to override which version of a 94 specific module will be used when more than one module 95 sharing the same name is processed by the 96 <command>depmod</command> command. It is possible to 97 specify one kernel or all kernels using the * wildcard. 98 <replaceable>modulesubdirectory</replaceable> is the 99 name of the subdirectory under /lib/modules (or other 100 module location) where the target module is installed. 101 </para> 102 <para> 103 For example, it is possible to override the priority of 104 an updated test module called <command>kmod</command> by 105 specifying the following command: "override kmod * extra". 106 This will ensure that any matching module name installed 107 under the <command>extra</command> subdirectory within 108 /lib/modules (or other module location) will take priority 109 over any likenamed module already provided by the kernel. 110 </para> 111 </listitem> 112 </varlistentry> 113 </variablelist> 114 </refsect1> 115 116 <refsect1><title>COPYRIGHT</title> 117 <para> 118 This manual page Copyright 2006-2010, Jon Masters, Red Hat, Inc. 119 </para> 120 </refsect1> 121 <refsect1><title>SEE ALSO</title> 122 <para> 123 <citerefentry> 124 <refentrytitle>depmod</refentrytitle><manvolnum>8</manvolnum> 125 </citerefentry> 126 </para> 127 </refsect1> 128</refentry> 129
