Hi Jonas,
Long time, no speak.

Hmm, zeroconf doesn't start at system boot time but when an interface is
'ifup'd. It only starts (or should start) a daemon for interfaces which
are listed as 'up' in /etc/network/ifstate when it is installed (on the
presumption that you installed it and want to benefit from it for
currently available interfaces).
I am also wondering what would bring zeroconf into a chroot environment.

I don't actually see a section in the online policy which talks about
policy.d -- however it has been a long time since I've read it. Pointers
welcome.
There are a few options:
- modify /etc/default/zeroconf and uncomment DISABLE
- create a file called /var/run/zeroconf.$IFACE.pid, which will
cause /etc/network/if-up.d/zeroconf to not run (well 0.8-2
won't).
- determine why the chroot thinks that a network interface is
operational and fix that
- work out the reason that zeroconf is being brought into the
chroot and stop that from occuring
I think I've listed the options from easiest to hardest. I can't think
of a way of having zeroconf run via /etc/init.d/ and properly operating
(it is supposed to survive ifup/ifdown cycles).
Your thoughts would be appreciated.
Regards,
Anand
