The apparmor policy already allows for loading libraries under the install
directory, so there should be no adjustments needed for policy. aa-exec-click
needs to follow upstart-app-launch for updating LD_LIBRARY_PATH and
QML2_IMPORT_PATH, but I'm not sure how to do that yet. upstart-app-launch uses
dpkg-architecture -qDEB_BUILD_MULTIARCH to generate the triplet during the
build, but I need to determine the triplet at runtime because click-apparmor is
'Architecture: all' (and therefore I can't set it during the build), and I'm not
sure yet how to properly find the triplet at runtime on the readonly image yet.
Suggestions welcome-- I just don't want to repeat the logic in dpkg-architecture
if I don't have to.
