The following commits added support for runtime resource overlays. New command line tool 'idmap' * 65a05fd56dbc9fd9c2511a97f49c445a748fb3c5 Runtime resource overlay, iteration 2 * 48d22323ce39f9aab003dce74456889b6414af55 Runtime resource overlay, iteration 2, test cases * ad6ed950dbfa152c193dd7e49c369d9e831f1591 During SELinux tightening, support for these runtime resource overlays was unknowingly broken. Fix it. This change has been tested by hackbod and she reports that everything is working after this change. I haven't independently verified the functionality. Test cases are available for this by running: * python frameworks/base/core/tests/overlaytests/testrunner.py Change-Id: I1c70484011fd9041bec4ef34f93f7a5509906f40
