By accident, I noticed that if you install a new kernel extension on 10.8 using an installer package, Installer will update the kext cache for you even if you don't touch /System/Library/Extensions. Is this behavior intended to be relied upon?

Upon investigating, I noticed that the timestamp of /System/Library/Extensions did in fact get updated, which may or may not have caused the system to update the kext cache. This might be a coincidence involving the timestamp of /System/Library/Extensions inadvertently getting modified by something else in my installer script, in which case the answer to the question is definitely 'no'.

I did some more testing, and now I am sure that my install scripts were inadvertently touching /System/Library/Extensions. So, if you want the kext cache updated, touch /System/Library/Extensions explicitly, just to be sure.
