12.4. kmod
The more "reference" kernel.org implementation of lsmod, insmod, rmmod, etc.: https://git.kernel.org/pub/scm/utils/kernel/kmod/kmod.git
Default implementation on desktop distros such as Ubuntu 16.04, where e.g.:
ls -l /bin/lsmod
gives:
lrwxrwxrwx 1 root root 4 Jul 25 15:35 /bin/lsmod -> kmod
and:
dpkg -l | grep -Ei
contains:
ii kmod 22-1ubuntu5 amd64 tools for managing Linux kernel modules
BusyBox also implements its own version of those executables, see e.g. modprobe. Here we will only describe features that differ from kmod to the BusyBox implementation.
