Description=Disable the loading of modules to the kernel after startup. This could be malicious.
After=systemd-modules-load.service
Before=sysinit.target
# This functionality is implemented with this and not directly in the sysctl config is
# to allow systemd-modules-load.service to load the modules with no problem but
# to disallow anyone else do the same after the system boots up.
