If the sdcard gets unmounted, any process with an open file handle to it gets killed.
Letting the system process be killed was considered a bad thing. To avoid that, the system process (which is to say any system process) is not allowed to access the SD card. FYI, you probably will not be able to install your apk with the system uid on most secured devices, unless you are in possession of the system certificate for the devices on which you want to deploy. What exactly do you need to access in the /system folder? You do know it's mounted read-only, right? Technically, anything regarding the system folder is beyond the bounds of discussion of android-developers which is supposed to be confined to the SDK APIs.
