A system administrator has compiled and installed a new kernel module from source to support a custom piece of hardware. To ensure the system can automatically handle the module's dependencies when it is loaded with modprobe in the future, which command must the administrator run?
lsmod
insmod
modinfo
depmod
The correct command is depmod. The depmod command creates a list of module dependencies by analyzing the modules located in /lib/modules/<kernel-version>. This process generates a file, typically modules.dep, which modprobe uses to understand module relationships and load any required dependency modules automatically. After installing a new module, running depmod is essential to update this dependency list for the system. insmod is a lower-level command that inserts a single module into the kernel but does not resolve its dependencies. modinfo is used to display information about a specific module. lsmod is used to list the modules currently loaded into the kernel.
