Hello,

first of all, sorry, this email got a little longer than I thought.

I think I have found two _separate_ bugs within the latest dhcpcd
versions 7.2.2 and 6.11.7 when I tested the following setup:

dhcpcd-6 is only getting security fixes right now.

##
## BUG 1
##

Missing DNS search domains with dhcpcd-6.11.7.

....

Same setup with dhcpcd-7.2.2 and I see all 4 dummy domains:

/etc/resolv.conf:
# Generated by dhcpcd from eth0.dhcp6, eth0.ra
# /etc/resolv.conf.head can replace this line
search from-dhcpd.org radvd1.org radvd2.org radvd3.org
nameserver fd00:1234::1
# /etc/resolv.conf.tail can replace this line

So dhcpcd-7 is fine, nothing to fix here.

##
## BUG 2
##

Stateless DHCPv6 seems to be broken in dhcpcd-7.2.2 as it never sends
any INFORM6 message but always wants to request an IPv6 address.

This has been fixed here:

Let me know if that works for you!
