def setup(**_kwargs)
  Kernel.raise HostBootsnapSetupError, <<~MSG
    Bootsnap.setup was called while TAPIOCA_RBS_CACHE=1 is set. Tapioca already
    configured bootsnap with a dedicated cache directory; re-running setup
    would overwrite that config and start writing rewritten iseqs into your
    host's cache.

    Gate your host's Bootsnap.setup on the env var, e.g. in config/boot.rb:

      require "bootsnap/setup" unless ENV["TAPIOCA_RBS_CACHE"] == "1"
