[Bug 18195] Re: dhcp search can't be avoided during installation

[Colin Alston]

So even if you pass a full set of netcfg parameters for a static network
config like...

auto=true interface=eth0 debian-installer/locale=en_US console-setup/layoutcode=us console-setup/ask_detect=false hostname=test1 domain=foo.net netcfg/disable_dhcp=true netcfg/get_ipaddress=192.168.0.3 netcfg/get_netmask=255.255.255.0 netcfg/get_gateway=192.168.0.1 netcfg/get_nameservers=8.8.8.8 url=http://bl
ahblah/preseed

Despite setting the interface, despite giving it all the necessary info
to obtain the preseed, and despite explicitly setting disable_dhcp the
Ubuntu installer - 5 years after this bug was reported - still tries to
do DHCP configuration, and requires manual intervention to select a
manual network configuration in which case only then it happily uses the
options already given to it.

What. The....

Title:
  dhcp search can't be avoided during installation

Status in “netcfg” package in Ubuntu:
  Triaged

Bug description:
  During installation, one cannot choose to NOT use dhcp to configure the network
  settings.

  This was problematic for me because the computer I was installing ubuntu on was
  in a network which had a DHCP server, but was not supposed to use it (instead it
  was supposed to have a specific static IP).  During the install, it obtained an
  (incorrect) IP from the DHCP server.  While one might debate the wisdom of the
  network administrator's overall design in this case, it is a valid scenario that
  caused me trouble.

  Adding an option to the installation -- before the DHCP search begins -- to
  manually configure network settings would fix this.
