  def caveats
    <<-EOS.undent
      In order for FUSE-based filesystems to work, the fuse4x kernel extension
      must be installed by the root user:
        sudo cp -rfX #{kext_prefix}/fuse4x.kext /System/Library/Extensions
        sudo chmod +s /System/Library/Extensions/fuse4x.kext/Support/load_fuse4x
    EOS
