I put Leo4All on the USB stick, it works until I change something in the Extensions. How can I recreate the Extensions.mkext file? kextcacche -k /System/Library/Extensions won't work, even if I boot in single user mode and set the stick to read/write mode. How can I access full read/write access during the normal boot process? Is theresome thing like a startup-sequence or an autoexec.bat?
