# To build FuzzContainer2 we need to prepare a few things:
# We change the name of the cmd/containerd package
# so that we can import it.
# We furthermore add an exported function that is similar
# to cmd/containerd.main and call that instead of calling
# the containerd binary.

# In the fuzzer we import cmd/containerd as a low-maintenance
# way of initializing all the plugins.
