Let the system pull required kernel modules and their dependencies automatically. 26.11.2025 | reading time: 2 min Want the kernel to load a module and everything it needs without manual labor? modprobe consults the dependency map and inserts required modules for you, which makes managing filesystem, network, and hardware modules far simpler than calling insmod for each file. See it load itself Try a concrete run that shows dependencies being pulled: ```bash $ sudo modprobe vfat $ modprobe --show-depends vfat insmod /lib/modules/$(uname -r)/kernel/fs/fat/fat.ko insmod /lib/modules/$(uname -r)/kernel/fs/fat/vfat.ko insmod /lib/modules/$(uname -r)/kernel/fs/nls/nls_utf8.ko $ lsmod | grep -E "vfat|fat|nls" vfat 20480 1 fat 86016 1 vfat nls_utf8 16384 1 ``` This demonstrates that loading the filesystem module automatically brought in its helper modules. Options and pitfalls Use `modprobe --show-depends` to preview what will be inserted, `modprobe -n` for a dry run, and `modprobe -r` to remove a module and its dependents; remember that modprobe expects a valid modules.dep map and will fail silently or leave gaps if that map is stale or missing, so run `sudo depmod -a` after installing new modules or kernels and prefer modprobe over insmod when dependencies matter. Where it matters most System boot, initramfs creation, container hosts, and driver packaging all rely on correct dependency handling: place persistent requests in `/etc/modules-load.d/`, adjust blacklists in `/etc/modprobe.d/`, and include `depmod -a` in kernel install workflows to keep module resolution reliable. Next steps Explore modprobe on a test machine, practice updating modules.dep with depmod, and add safe module loading to your boot scripts; if you want structured learning and exam preparation for Linux topics like kernel modules, consider deepening your skills toward CompTIA Linux+ or LPIC-1 with intensive training at bitsandbytes.academy.
