I want to make a script to update Extensions.mkext and then copy/overwrite mach_kernel + Extensions.mkext + Library/Preferences/SystemConfiguration/com.apple.Boot.plist + System/Library/CoreServices/SystemVersion.plist
and set permissions.
So that its a simpler matter when ever I update anything. Anyone know how to do this I had a couple of goes at writing a script but its something I haven't done for about 8 years so not exactly my strong point.

It would be fantastic if this script could mount and unmount my boot partition.
