Rust modules are different from C++ modules in that they will install their transitive shared libs alongside a binary. C++ modules don't do this, you have to install the transitive shared lib manually. (but they do install direct shared libs) It does this by using InstallDepNeeded, a mechanism that adds dependencies from installed files to the installed copies of dependencies if InstallDepNeeded() returns true. This mechanism does not end up tracking the installed files all the way to FULL_SYSTEMIMAGE_DEPS. We're attempting to make FULL_SYSTEMIMAGE_DEPS more accurate so that we can track the files that should be installed properly, and remove the need for `m installclean`. Listing the libraries a binary uses in LOCAL_SHARED_LIBRARIES does properly track them and end up listing them in FULL_SYSTEMIMAGE_DEPS. Bug: 205632228 Test: Building the systemimage with a change to delete anything not in FULL_SYSTEMIMAGE_DEPS Change-Id: I4ba75b40b3ac77250297209a851bc9ba377782f5
