dhcpcd-discuss

Hi,

OpenBSD 6.2
dhcpcd-6.11.5p4

dhcpcd.conf

noipv6rs
ipv6only
duid
persistent
option rapid_commit
require dhcp_server_identifier
nohook lookup-hostname resolv.conf
allowinterfaces em0 em2

interface em2
        ia_pd 1 em0/1

All works as expected but I wonder what those log messages mean, do I 
have to be concerned?
