> How disruptive are switch config changes? If I edit /etc/network/interfaces to add a new port, vlan, etc They are seamless as long as your configuration does not do something stupid like tear down interfaces to reconfigure them. The switch takes no noticeable time to program from the Linux space to the ASIC > - does a `systemctl restart networking` (or whatever equivalent) bounce ports or halt switching for a moment while changes are applied? "systemctl restart networking" will typically blow away even the well most well configured systems in my experience. In the post I suggest using ifupdown (the first one), since it's the most "easy" to debug, but I'm sure networkctl works too, with a healthy amount of systemd restraint
