    Hi Aitor.

    According to https://cumulusnetworks.com/blog/ifupdown2/ ,
ifupdown2 has been developped to replace ifupdown in switches, in which
the configuration can be pretty complicated with dependency chains
between physical and logical interfaces such as bridges. IIUC, it is
supposed to allow dynamic changes of the configuration without needing
to stop/start the interfaces. They claim it is backward-compatible with
ifupdown. I guess it allows to do complicated things but I also guess it
requires some serious learning. It does not seem fitted for a laptop or
a simple server. We know that ifupdown cannot achieve all imaginable
configurations, but it is a relatively simple tool usable in most usual
