I'd be not doing this for a while since some of this code doesn't compile on host and libinit previously did. But after realizing the property_service.cpp (libinit) references symbols in init.cpp (init) and seeing a new linker error crop up due to that, it's time to make the fix. My only hold out previously was that libinit compiled on host bionic and some of init (builtins.cpp, etc) do not, however given that we don't actually have host bionic support or host bionic init tests, that isn't a good reason. We can and should mock out the libraries that aren't available with host bionic when ready. Test: build, unit tests, boot Change-Id: Ie49362ddb637924efc272540a4f32b693643fcdc
