Ah - seems the reply-to header has changed with the new list....

Hmm... I'm using the standard radmind.hook script which just removes  
the .mkext and .kextcache, but after this update (and one in the  
past) I found that there was still an old copy of System.kext loaded  
even after I manually nuked /S/L/Extensions.* and watched it rebuild  
them in verbose mode. The problem (which interestingly manifested as  
an inability to mount disk image files) went away when I deleted / 
System/Library/Caches/com.apple.kernelcaches.

So maybe just touching /S/L/Extensions is a more surefire way of  
doing this...

Also, I'm sure I remember there being a post action in the Apple  
update package that performed this function in the past. There's no  
such thing as far as I can tell in MacOSXUpd10.4.5PPC.pkg

How does Apple do it now?
