Reboots fail with eapol WAN interface
Closed, ResolvedPublicBUG
Actions

Description

Took the time to upgrade a router I had with an eapol configured WAN interface using vif 0 from a 1.4 rolling release, specifically 1.4-20230714, to the release candidate. During this reboot, the device failed to boot properly as eth0.0 wasn't yet a valid interface. In the 1.4 rolling release, I was able to rectify boot issues by affixing hw-id, but in this rc, the hw-id seems irrelevant.

I beleive there are some existing bug reports around interface ordering and configuration at boot time, but given this was eapol specific, I wanted to open a seperate bug report here.

The specific service that appears to cause the config to fail here is the dynamic dns client.

This is actually caused by a missing priority value from ddclient. This is an ancient bug indeed.

Reason is the VLAN interface is not yet created, when ddclient tries to consume it during boot.
