+ * The idea is that modprobe will look first if the
+ * modules are compiled for the current release of the kernel.
+ * If not found, it will look for modules that fit for the
+ * general kernelversion (2.0, 2.2 and so on).
+ * If still not found, it will look into the default release.
+ * And if still not found, it will look in the other directories.
+ *
+ * The strategy should be like this:
+ * When you install a new linux kernel, the modules should go
+ * into a directory related to the release (version) of the kernel.
+ * Then you can do a symlink "default" to this directory.
+ *
+ * Each time you compile a new kernel, the make modules_install
+ * will create a new directory, but it won't change thee default.
+ *
+ * When you get a module unrelated to the kernel distribution
+ * you can place it in one of the last three directory types.
+ *
+ * This is the default strategy. Of course you can overide
+ * this in /etc/modules.conf.
+ *
+ * 2.3.15 added a new file tree walk algorithm which made it possible to
+ * point at a top level directory and get the same behaviour as earlier
+ * versions of modutils. 2.3.16 takes this one stage further, it
+ * removes all the individual directory names from most of the scans,
+ * only pointing at the top level directory. The only exception is the
+ * last ditch scan, scanning all of /lib/modules would be a bad idea(TM)
+ * so the last ditch scan still runs individual directory names under
+ * /lib/modules.
+ *
+ * Additional syntax:
+ *
+ * [add] above module module1 ...
+ * Specify additional modules to pull in on top of a module
+ *
+ * [add] below module module1 ...
+ * Specify additional modules needed to be able to load a module
+ *
+ * [add] prune filename ...
+ *
+ * [add] probe name module1 ...
+ * When "name" is requested, modprobe tries to install each
+ * module in the list until it succeeds.
+ *
+ * [add] probeall name module1 ...
+ * When "name" is requested, modprobe tries to install all
+ * modules in the list.
+ * If any module is installed, the command has succeeded.
+ *
+ * [add] options module option_list
+ *
+ * For all of the above, the optional "add" prefix is used to
+ * add to a list instead of replacing the contents.
+ *
+ * include FILE_TO_INCLUDE
+ * This does what you expect. No limitation on include levels.
+ *
+ * persistdir=persist_directory
+ * Name the directory to save persistent data from modules.
+ *
+ * In the following WORD is a sequence if non-white characters.
+ * If ' " or ` is found in the string, all characters up to the

+/*
+ modutils requires special processing during the file tree walk
+ of /lib/modules/<version> and any paths that the user specifies.
+ The standard ftw() does a blind walk of all paths and can end
+ up following the build symlink down the kernel source tree.
+ Although nftw() has the option to get more control such as not
+ automatically following symbolic links, even that is not enough
+ for modutils. The requirements are:
+
+ Paths must be directories or symlinks to directories.
+
+ Each directory is read and sorted into alphabetical order
+ before processing.
+
+ A directory is type 1 iff it was specified on a path statement
+ (either explicit or default) and the directory contains a
+ subdirectory with one of the known names and the directory name
+ does not end with "/kernel". Otherwise it is type 2.
+
+ In a type 1 directory, walk the kernel subdirectory if it exists,
+ then the old known names in their historical order then any
+ remaining directory entries in alphabetical order and finally any
+ non-directory entries in alphabetical order.
+
+ Entries in a type 1 directory are filtered against the "prune"
+ list. A type 1 directory can contain additional files which
+ are not modules nor symlinks to modules. The prune list skips
+ known additional files, if a distribution wants to store
+ additional text files in the top level directory they should be
+ added to the prune list.
+
+ A type 2 directory must contain only modules or symlinks to
+ modules. They are processed in alphabetical order, without
+ pruning. Symlinks to directories are an error in type 2
+ directories.
+
+ The user function is not called for type 1 directories, nor for
+ pruned entries. It is called for type 2 directories and their
+ contents. It is also called for any files left in a type 1
+ directory after pruning and processing type 2 subdirectories.
+ The user function never sees symlinks, they are resolved before
+ calling the function.
+
+ Why have different directory types? The original file tree
+ walk was not well defined. Some users specified each directory
+ individually, others just pointed at the top level directory.
+ Either version worked until the "build" symlink was added. Now
+ users who specify the top level directory end up running the
+ entire kernel source tree looking for modules, not nice. We
+ cannot just ignore symlinks because pcmcia uses symlinks to
+ modules for backwards compatibility.
+
+ Type 1 is when a user specifies the top level directory which needs
+ special processing, type 2 is individual subdirectories. But the
+ only way to tell the difference is by looking at the contents. The
+ "/kernel" directory introduced in 2.3.12 either contains nothing
+ (old make modules_install) or contains all the kernel modules using
+ the same tree structure as the source. Because "/kernel" can
+ contain old names but is really a type 2 directory, it is detected
+ as a special case.
