I think the error comes from inet6.defn:
echo 'No DHCPv6 client software found!' >/dev/stderr; false
and for some reason systemd does not let that file exist.
I'm not sure why you use /dev/stderr instead of &2 in the shell script.
I do have a /dev/stderr btw and it's a symlink to /proc/self/fd/2.
The reason this error gets tripped is because I was trying out dhcpcd and
ifupdown does not support that for IPv6
but that is for another bug report.
