Hello there, with the help of James I was finally able to properly compile ubuntu packages to carry local patches in my Kilo installation. I documented the all process here: https://github.com/zioproto/ubuntu-cloud-archive-vagrant-vm I hope this is useful for everyone. The notes I wrote can be still improved. The best would be to make the process easy for everyone, so that we can easily create a workflow to propose patches upstream to the ubuntu packages. Thank you ! Saverio
