depmod
depmod [options] modules
System administration command. Create a dependency file for the modules given on the command line. This dependency file can be used by modprobe to automatically load the relevant modules. The normal use of depmod is to include the line /sbin/depmod -a in one of the files in /etc/rc.d so that the correct module dependencies will be available after booting the system.
Options
Create dependencies for all modules listed in /etc/modules.conf.
Specify a base directory to use instead of /lib/modules.
Print a list of all unresolved symbols.
Debug mode. Show all commands being issued.
Print help message, then exit.
Write dependency file to standard output.
Don't display error messages about missing symbols.
Allow root to load modules not owned by root.
Write error messages to the syslog daemon instead of to standard error.
Print a list of all processed modules.
Check timestamps and update the dependency file if anything has changed.
Use the specified configuration file instead of /etc/modules.conf. May also be set using the MODULECONF environment variable.
Use the specified kernel symbol file to build dependencies. Usually this is either a copy of a system's System.map file or the output of /proc/ksyms.
Print version number.
Files
Information about modules: which ones depend on others, and which directories correspond to particular types of modules.
