Previously, we ran modprobe command for every .ko file listed in init.insmod.*.cfg. Let's move to a different approach where we call modprobe with the following command line. modprobe -b --all=/vendor/lib/modules/modules.load This will insmod all modules listed in modules.load except for those that are mentioned in the blocklist at /vendor/lib/modules/modules.blocklist A common reason for a module to be on the blocklist is that it must only be loaded under a certain condition like when a specific service is launched.
