# These are some extra files that are included in the test package under
# lib/config_test, for use in the config_test unit test. This is necessary
# because the library loader must be able to load the files using
# OPEN_RIGHT_EXECUTABLE/VMO_FLAG_EXEC, and the easiest way to provide a test
# directory that supports that is a real pkgfs directory.
# TODO(https://fxbug.dev/42061196): Replace this with a pseudo-directory backed by the Rust VFS.
