Support for dynamic command execution based on cumulus version

[sukhmeetbawa]

I am trying to make a model file for cumulus where, different commands are executed based on the cumulus version whether net command is available or nv command is available.

cmd 'cat /etc/cumulus/etc.replace/os-release' do |cfg|
    @cumulus_version = cfg.match(/^VERSION_ID=(\d+)\./)[1]
    cfg = add_comment('VERSION') + cfg
  end

this it is the code for that in the model file. The problem is @cumulus_version value is not being read in the following model file. something like this

if @cumulus_version == '4'
  cmd 'net show lldp' do |cfg|
    cfg = add_comment('LLDP') + cfg
  end
end

I want to know if this is even possible?
