[Pkg-utopia-maintainers] Bug#409513: ifup and ifdown slow becouse of avahi-deamon script

[Andrzej Zięba]

Package: avahi-daemon
Version: 0.6.16-2

Configuring network interfaces at boot and deconfiguring at shut down
takes 10s or so.

If I use 'ifdown -a' and next 'ifdown -a -v' I get the fallowing output:

Configuring interface lo=lo (inet)
run-parts --verbose /etc/network/if-pre-up.d
run-parts: executing /etc/network/if-pre-up.d/wireless-tools
ifconfig lo 127.0.0.1 up
run-parts --verbose /etc/network/if-up.d
run-parts: executing /etc/network/if-up.d/avahi-daemon
run-parts: executing /etc/network/if-up.d/mountnfs
Configuring interface eth0=eth0 (inet)
run-parts --verbose /etc/network/if-pre-up.d
run-parts: executing /etc/network/if-pre-up.d/wireless-tools

ifconfig eth0 192.168.1.98 netmask 255.255.255.0 broadcast 192.168.1.255
                up
  route add default gw 192.168.1.1  eth0
run-parts --verbose /etc/network/if-up.d
run-parts: executing /etc/network/if-up.d/avahi-daemon
run-parts: executing /etc/network/if-up.d/mountnfs

The time out takes place at the first call to
/etc/network/if-up.d/avahi-daemon before eth0 is actually up.

As far as I can tell the script does not recognise if it is called while
lo is initialised.
Adding something like
[ "$IFACE" != "lo" ] || exit 0
to /etc/network/if-up.d/avahi-daemon could solve the problem at boot.

I think that the long time out at system shut down happens because 
avahi-daemon script is called from /etc/network/if-post-down.d/ and not 
from /etc/network/if-down.d. In current order the avahi-daemon script 
gets executed when eth0 is already down. So whatever this script tries 
to do, it waits 10s before failing. So the link from 
/etc/network/if-post-down.d/ should be moved to /etc/network/if-down.d.
These fixes work with single network adapter, I cant say if it would 
work in other conditions.

And one more thing. If I run 'ps -A' it appears that avahi-daemon has 
two instances.
