$ wc -l /var/log/

It would be nice to suppress those lines if those could be safely ignored. It would make troubleshooting easier when something wrong happened on commissioning.

tl;dr: dhclient -6 should be less spam-chatty in the presence of no ipv6 support.
If dhclient logged that as one message, instead of 9 messages, then syslog would compress the output.
The easiest way that I've seen to reproduce this is to boot with ipv6.disable=true on the kernel command line.
Nobuto: do you have ipv6 disabled via the kernel command line? (This is known to cause various issues for a number of daemons.)
