I also notice that ddclient has a similar problem.

ddclient[1710]: FAILED:   Unable to obtain information for 'pppoe0' -- missing ip or ifconfig command

This might be a problem that's specific to me. I don't know why every systemd start too early.

Thanks, will investigate this.

@sdev, this will require adjusting on-dhcp-event.sh. I have a hacky local version that writes to /etc/hosts that partially works -- the $domain part is not picked up (which I suspect could be related to how kea-dhcp4.conf is generating the FQDN).

Do you want me to raise a draft PR for you to review?

By all means, thank you!

@Viacheslav, updated PR https://github.com/vyos/vyos-1x/pull/2562

Looks like, we still need to keep /etc/avahi/services because avahi-daemon chroot to that location at startup. This is set up at build time via AVAHI_CONFIG_DIR and there is no way to change it at runtime.

Pretty sure some preceding backports are pending. Please give me a couple of days. I plan to sync up 1.4 with 1.5 and update the docs.
