Hello I am writing an application that for users convenience has a button "Uninstall". Inside, this "uninstaller" stops several launchd services, "kextunloads" a driver, deletes this driver and services and finally is supposed to delete itself. In any sane operating system it is impossible (at least, directly) for an application to remove a file that is running. Hence i am searching for a detour.
The uninstaller is a helper tool, which has a suid bit set. I am fork/exec'ing this helper tool when a user clicks "Uninstall" button in System Preferences custom preference pane. The only way i am seeing how to completely remove everything my installer had installed, and to remove the preference pane (that contains settings and this "Uninstall" button) itself, is to delegate "unlinking" of files to some external tool - like AppleScript (fork/exec the "osascript" and terminate the parent process). But then, i am unsure about privileges issue. Should i be calling osascript with AuthorizationExecuteWithPrivileges? But the what happens if my uninstaller application terminates right after it calls this function? (i need to terminate it, to let the script delete uninstaller's executable). Could you give me some hints on where to look and what would be the best approach?
