systemd-networkd only deals with .netdev and .network files; .link files
are handled by udev
This occurs during boot, before systemd-networkd starts.
cloud-init-local.service runs before network-pre.target and writes out a
/etc/netplan/nplan.yaml,
invokes `netplan generate` which writes out
/run/systemd/network/10-netplan-xx.{.link,network,netdev}
as needed; however, the cold plug of devices (systemd-udev-trigger.service)
happens prior to
cloud-init-local.service; as it's required for mounting the rootfs among
other things.
The udev service is also used for device renaming, which would need to
occur before starting
networkd. As such, in cloud-init-local, after generating netplan
configuration, we re-trigger
the net subsystem events which *should* process any .link files.
The bug, I believe, is that during cloud-init-local execution, udev does
*not* process the .link files
prior to starting systemd.
I'm currently working around this using the side-effect of using udevamd
test-builtin setup_net_link
which will process the .link files.
I'll collect a journal and attach it.
