I have a server running Arch and after updating today, I can't connect to it. It is OVH Kimsufi, so I am able to access it via rescue netboot.
I put
Environment=SYSTEMD_LOG_LEVEL=debug
in
/usr/lib/systemd/system/systemd-networkd.service
/usr/lib/systemd/system/systemd-networkd-wait-online.service
/usr/lib/systemd/system/systemd-udevd.service
I am including the relevant bits below. Any ideas on how to dig further? I see it says eth0 has operational state 'off' meaning it is powered down.
