Type in the simplest command, including any switchs, to rebuild the modules.dep file after you
have made changes to the modules.conf file.
Answer: depmod -a
depmod creates a list of module dependencies, by reading each module under
/lib/modules/version and determining what symbols it exports, and what symbols it needs. By
default this list is written to modules.dep in the same directory. The normal use of depmod is to
include the line /sbin/depmod -a in one of the files in /etc/rc.d so the correct module dependencies
will be available after booting the system. depmod -e prints a list of all unresolved symbols.
