Looks like this has been fixed in upstream systemd, so there's probably not a lot that we can do on the Netplan side.

The upstream bug is tagged for a stable backport, so we *should* get this soon-ish in noble.

Would it be possible to backport this to 22.04 as well? We are currently using very hacky workarounds with Netplan.io and networkctl to prevent this bug from being triggered and causing downtime.

Bump this is also affecting us causing quite a lot of downtime just to add a vlan interface
