I recently upgraded a router running 1.4-rolling-202308240020 to the latest 1.5-rolling-202312010026 and it failed to boot with a Starting VyOS router: migrate configure failed! failure.
I tried booting with the grub option vyos-debug-config and it said it collected data to /tmp/boot-config-trace, however, the vyos:vyos login would not work (as it has in the past), so I could not see the specific error data. (as an aside, it would've been very helpful if this was stored to a persistent location like /log)
I was able to strip the config file down to the minimal necessary to boot and added in one section at a time until I discovered the problem. It appears the peth0 interface isn't available at the time the dynamic dns config is loaded...
This appears to be a timing issue that did not exist in the prior version, but even so, it doesn't seem like this should prevent the system from booting, nor prevent the vyos-debug-config option from enabling the vyos:vyos login.

Removing the address peth0 section from service dns dynamic enables the system to boot.
I can also add the address peth0 section back after boot and commit without any issues, but cannot save it.
