  params_string = params.map { |k, v| "#{k}=#{v}" }.join(" ")
  new(name, params_string)
end

.write_options(drivers) ⇒ Object

Writes driver options to the underlying system

Parameters:

def write_options(drivers)
  drivers.each(&:write_options)
  commit
end

Instance Method Details

#write_options ⇒ Object

Adds driver parameters to be written to the underlying system

Parameters are not written to disk until Y2Network::Driver.commit is called. The reason is that writing them is an expensive operation, so it is better to write parameters for all drivers at the same time.

You might prefer to use write_options instead.
