aha, ali vazi samo za panter. evo sta kaze amit singh sa www.kernelthread.com:

"/System/Library/Extensions/BootCache.kext is the location of the kernel extension implementing the cache while Contents/Resources/BootCacheControl within that directory is the user-level control utility (it lets you load the playlist, among other things). The effectiveness of BootCache can be gauged from the following: in a recent update to "Panther", a reference to BootCacheControl was broken. BootCache is started (via the control utility) in /etc/rc, and a prefetch tag is inserted (unless the system is booting in safe mode). /etc/rc looks for BootCacheControl in the "kext" directory, as well as in /usr/sbin, and finds it in the former (it doesn't exist in the latter). However, another program (possibly loginwindow.app) accesses /usr/sbin/BootCacheControl directly, and does not find it. For what it's worth, making BootCacheControl available in /usr/sbin, say via a symlink, reduces the boot time (measured from clicking on the "Restart" confirmation button to the point where absolutely everything has shown up on the system menu) from 135 seconds to 60 seconds on one of my machines!"

eto, sad znamo i zasto :)
