  def caveats

      For #{name} to be able to work properly, the filesystem extension and
      preference pane must be installed by the root user:

        sudo cp -pR #{prefix}/System/Library/Filesystems/fuse-ext2.fs /Library/Filesystems/
        sudo chown -R root:wheel /Library/Filesystems/fuse-ext2.fs

        sudo cp -pR #{prefix}/System/Library/PreferencePanes/fuse-ext2.prefPane /Library/PreferencePanes/
        sudo chown -R root:wheel /Library/PreferencePanes/fuse-ext2.prefPane

      Removing properly the filesystem extension and the preference pane
      must be done by the root user:

        sudo rm -rf /Library/Filesystems/fuse-ext2.fs
        sudo rm -rf /Library/PreferencePanes/fuse-ext2.prefPane
    EOS

  test do
    # Can't test more here as an ext2 image mounting test
    # would require fuse-ext2.fs to be installed (see caveats)
