Hi Roy,

thank you for kindly offering your help!

I'll come up with a log file later; I've now noticed that while dhcpcd used to use the sylog call there seems to be some change after 6.7.1 (yeah, really old, I know) that now causes the logging output of dhcpcd to become buffered when run inside a simple docker container that uses the console for syslog logging. With dhcpcd 6.7.1 the logging output is synchonous, as need for debugging. Any idea what may cause this changed behavior? I've tested both very recent dhcpd versus 6.7.1 in the same container and they behave differently. *scratch* *scratch*

Best regards,
Harald

2. Does dhcpcd also time out and terminate without a fallback

preferably without a fallback configuration (unless this could be an
empty one)?
Not with DHCPv6.
Where-as there's a clear use case for fallback configs with IPv4, there
is little for IPv6 because the whole protocol falls apart if there is no
working advertising router.

My rationale here is that I would like to make the routers work without
having to up/down interfaces if possible, and without any dependy on the
startup sequence.
I agree entirely.
Lets see what the logs say and work it out from there.
