Which utility is used to create or update the modules.dep file? Type the command only.
Which utility is used to create or update the modules.dep file? Type the command only.
Correct Answer:
depmod
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.
