[Bug 987761] Re: precise-server-i386 installation hangs upon retrying the auto network configuration

[Vincent Fortier]

Having similar problem.

Extending the waiting time for DHCP netcfg/dhcp_timeout=120
(installation option) or ensure portfast is activated on the gigabit
swtich will ensure dhcp works out properly.  Otherwhise this happends on
my x86_64 arch in both virtual and physical environments.

Effectively swthing into a shell on screen 2 I could find 2 instances of rdnssd:
10240 root      8696 S  rdnssd -f -u root -r /tmp/rdnssd_resolv
10241 root    10796 S  rdnssd -f -u root -r /tmp/rdnssd_resolv

Killing the first one allowed the installer to continue.
