Examples:

compression_level 1

Parameters:

  • val (Integer) (defaults to: NULL) —

    level of compression (1, .., 9)

Returns:

      raise InvalidValue.new(:compression_level, "be an Integer between 1 and 9")
    end

    @compression_level = val
  end
end

#compression_params ⇒ String

  end
end

#create_deb_file ⇒ void

This method returns an undefined value.

Create the .deb file, compressing at gzip level 9. The use of the fakeroot command is required so that the package is owned by root:root, but the build user does not need to have sudo permissions.
