Clarify to a Linux customer just how do BSD/OSX drivers function

Linux drivers can be found in a kind of bit components (*.ko documents), which can be offered parameters when filled right into the bit and also generally stay in /lib/modules/<kernel version>.

What's the comparable setup for BSD/OSX? As an example, I've simply mounted MacFUSE and also have tough time recognizing just what did the installer took into my system.

I'm not exactly sure concerning various other BSD, yet OSX have bit expansions (called kext).

Kexts stay in /System/Library/Extensions/. Each of them is a folder, having tool summary and also guideline (those that makes a vehicle driver). Points in a kext demand ideal documents approvals (usually come from customer 0:0 with mask 755) for it to function.

After a kext remains in area, the OS will instantly load it on reboot (although occasionally promptly). Periodically you require to clear the kext cache (rm -r /System/Library/Extensions/Caches/) prior to the new kext will certainly function appropriately.
