Dear Maintainer,

This configuration used to work on wheezy:
iface eth0 inet6 static
    address 2001:0bc8:32b1::1
    netmask 64
    pre-up dhclient -cf /etc/dhcp/dhclient6.conf -pf /run/dhclient6.eth0.pid -6 -P eth0
    pre-down dhclient -x -pf /run/dhclient6.eth0.pid

with /etc/dhcp/dhclient6.conf containing:
interface "eth0" {
        send dhcp6.client-id ##REDACTED##;
	supersede dhcp6.name-servers ::1;
	supersede dhcp6.domain-searchi "mydomain.example.com.";
}

Since upgraded to jessie, I had to add "pre-up sleep 10" before dhclient
line. If not, dhclient give up with the following error and does not allow
static IPv6 to be configured:

dhclient: no link-local IPv6 address for eth0

I also tried to add "-w" option to dhclient line without effect.

Dhclient should wait link-local address to be ready and not give up
immediately (especialy with "-w" option).
I've found similar bug on Red-Hat bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=1130803
They don't seams to have issue an upstream bug.

Hi,

this bug still exists in Debian Stretch and Buster.
I have similar problem on my Freedombox running Debian Stretch.

Ubuntu tracker has the same issue [1] and they already have fix for
that [2]. I tried the patch and it works and solves problem for me.

1. https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1633479
2. https://launchpadlibrarian.net/289550738/suggested-fix.diff

This also requires the patch from this bug:
https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1718568

I created a patch that applies against isc-dhcp-4.3.5 that contains the two
patches mentioned in this bug.

Is there anything from preventing this from being included now?

Hi everyone! :-)

It would be really super cool if my predecessor's patch would be
included in the isc-dhcp-client package for Debian Buster.

We have tested the patch several times and considered it good.

Is that somehow possible?

Best regards,
Raphael Grewe
