I've heard this complaint before, but I still don't understand the reason. Even if we did look for KEXTs in /Library/Extensions, the ownership rules would be the same as /S/L/E, so its not like it would simplify installers at all.
Because the current situation breaks the implied logic of the system. Implicitly the logic is "System wide stuff apple needs is in System", "System wide stuff used by 3rd parties is in /Library", and "non system wide stuff is in your home directory". As things stand today if I want to know what third party kext are installed I first have to know enough about the system to know what kext's apple installs. I'm a little surprised you've never heard this argument. I clearly remember this issue being raised and discussed at the very first IOKit kitchens.
I definitely agree with Kevin's argument in that /Library is for 3rd party, site-specific, but site-wide installations. This is the philosophy used by SystemStarter, both /System/Library/StartupItems, and /Library/StartupItems are searched at startup. (in fact when conflicts are encountered, /Library/ wins).
Also, I think this made the safe-boot stuff fairly simple, we just ignore /Library/StartupItems during safe-boot.
Further, we are reserving /Library/Extensions for future use, so PGP is definitely at risk of not being forward-compatible.Huh? Out of curiosity, where was that documented?
My vote is to have /Library/Extensions searched at boot in addition to /System/Library/Extensions, both with the same strict permission requirements.LOL. Not exactly what I meant... I was talking about kext in /Library/Extensions being probed during booting, which is clearly not the case based on the above.Are kext that load during booting supported?Yes, I/O Kit does this all the time. KEXTs can also be loaded using kextload from a StartupItem.
