Preseeded installer uses avahi instead of waiting DHCP

[Дмитрий Огородников <dmitry.b.ogorodnikov@gmail.com>]

Hi all,

I have slow DHCP and TFTP-server with debian installer. Whet I try to
install Debian (squeeze 6.0.3), installer sets IP to 164.254.x.x
instead of waiting DHCP respond.

Adding "d-i netcfg/dhcp_timeout string 60" doesn't change this
behavior. Installer sets autoconfigured address quikly, so timeout
don't get expired.

So I look for preseed option that disables avahi.

Thanks in advance,
Dmitry.
